BioLogos and the age of the earth: Pushing an anti-biblical doctrine

by and Tas Walker

Published: 4 October 2012 (GMT+10)


BioLogos’ infographic “How we know the earth is old” annotated to show the errors and problems. click image to enlarge.

Recently, BioLogos published an infographic entitled “How do we Know the Earth is Old?” Many Christians have wondered what to make of this poster since BioLogos presents itself as an association of evangelical Christian academics committed to harmonizing science and conservative Christian faith. That sounds good, especially the word “conservative”, but their starting position is anything but orthodox. They promote evolution over millions of years, as taught by secular scientists, as truth, and that Christians must accept it. They do not concern themselves with how such acceptance undermines the authority and the message of Scripture itself.

Moses has a lot to say about the age of the earth, and ignoring this fact leads to heretical Christian teaching and very bad natural history.

To many the age of the earth may seem an innocuous topic but it has a massive impact on conservative Christian doctrine such as the integrity of the gospel. If the earth is billions of years old, as the BioLogos poster presents, then Jesus made mistakes in his teaching and the gospel is false. It is that simple, as we will see.

According to BioLogos, all we have to do is reinterpret Moses, Jesus, and Paul, and everything is harmonized. A historical Adam doesn’t matter, and Jesus’ Incarnation allows him to make errors concerning what the Father commanded him to say about the age of the world (Mark 10:6; Luke 11:50–51; cf. John 8:28). However, their ‘reinterpretations’ look nothing like what Moses, Jesus, and Paul actually said. Neither were such interpretations ever entertained in church history before the advent of long-age geology in the 18th century (on which see The Great Turning Point). The reasons are pretty obvious. If Jesus made mistakes, especially in his teaching ministry, then He is not perfectly trustworthy, as Christians have believed through the ages. If a historical Adam doesn’t matter, then the whole doctrine of salvation, as presented by the Apostle Paul, falls to pieces (see articles on Romans 5, Romans 8, and 1 Corinthians 15). One could say that there never has been a time when Jesus’ words about Moses have been more important for us to hear than now: “For if you believed Moses, you would believe me; for he wrote of me. But if you do not believe his writings, how will you believe my words?” (John 5:46–47).

Because of this, we will analyse the claims of this poster point by point and and method-by-method. As we will see, it is BioLogos’ practical rejection of Jesus’ words that has them denying foundational Christian doctrines. Moses has a lot to say about the age of the earth, and ignoring this fact leads to heretical Christian teaching and very bad natural history. The text of the BioLogos poster will be reproduced in red and our response in black.

How do we know the earth is old?

There are several reliable ways to accurately estimate the age of materials on earth. Some methods measure radioactive atoms that decay at steady and predictable rates; others count layers that grow or are deposited in recognizable yearly patterns.

The first mistake is in the first sentence. There is only one way to reliably know the age of anything and that is by eyewitness testimony, on the basis of their written records. That is how we know that the Gettysburg Address was delivered on the afternoon of Thursday, 19 November 1863, and that the Battle of Hastings began at about 9am on 14 October 1066. The Bible makes it abundantly clear that the truth of a matter is to be established on the basis of eyewitnesses (e.g. Deuteronomy 19:15, 2 Corinthians 13:1). BioLogos here claims that ages can be accurately estimated without eyewitnesses. So how are the ages established? They are assumed, as we will explain. That is what the poster does not say, that all such ages rely on unprovable assumptions about the past. The fact is that a person can obtain any age that they like depending on the assumptions that they make.

Not only did the ancient Israelites care about history—they cared about the historical reliability of their origins narrative too.

The methods described in this poster are what we could call the ‘observe and extrapolate’ methods of dating. These methods rely on three basic assumptions—(1) we can somehow know the initial conditions of the system from present observations, (2) the rate of change in the system currently observed is constant and measurable, and (3) the system is sufficiently resistant to interference that we are warranted in extrapolating the rate of change back thousands, millions, or even billions of years based on a few decades’ worth of data. As we shall see, all three assumptions are erroneous to various degrees in every method cited. Nevertheless, using this same approach to ‘dating’ as BioLogos accepts, a vast array of methods and indicators suggest a much younger age for the earth (see Age of the earth and ‘Young’ age of the Earth & Universe Q&A). This indicates that this question cannot be settled by doing science in the present, but by the historical method (see following).

What BioLogos doesn’t say in this poster is just as revealing as what they do. The Bible is not referenced once in this entire poster. Why? There is nothing in biblical chronology that supports an old earth. In order to accept the millions of years of secular evolution they must regard the Bible as irrelevant for chronology. The problem, of course, is that the Bible is full of chronological information, which is based on eyewitness testimony. Biblical chronology also provides a beginning for human history (Genesis 5:1–3) and an absolute beginning of time in Genesis 1:1 (cf. Exodus 20:8–11; Exodus 31:16–17)—both of which directly contradict old-age chronology. Humans, the earth, and the universe are all only thousands of years old, according to the Bible, not billions. This is precisely why this issue is so contentious.

This reveals perhaps the most fundamental assumption of all—that forensic science is always able to give us the right answer about what happened (when properly done and when conditions are conducive to such methods, e.g. long-agers acknowledge that certain rocks are useless for dating, usually because of open-system effects). In practice, this means that the claims people make based on forensic science are accepted above the plain teaching of Scripture. As such, BioLogos judges and interprets Scripture based on long-age chronology in practical violation of sola scriptura. If BioLogos did not believe these claims were reliable they would question on the long-age chronology. Shouldn’t God have the final say? And herein lies the problem.

BioLogos thinks that God has nothing to say about natural history, or that what He said was couched in ‘pre-scientific’ language that bears little relation to historical reality in anything other than a ‘once upon a time’ sort of way.1 God spoke in fables and parables, and never actually told a story true to historical reality when it came to origins. Apparently, the ancients thought that fables and parables were more ‘true’ than accounts of history—it’s only we ‘post-Enlightenment’ folk who are interested in ‘what really happened’.

The ancient Israelites were perhaps less concerned with precision than we typically are, and they often recounted history as much for the moral lessons as for what actually happened. But where would the moral implications be if the history wasn’t true; if it was just a fable or parable, or, worse still, mistakes or lies? The ninth commandment says: “You shall not bear false witness” (Exodus 20:16). A witness tells what happened. Therefore, the ancient Israelites must have cared about history, after all—especially in legal contexts. And in this regard, it is significant that the 10 commandments are in fact a part of a legal covenant between Israel and God. Just a few verses before God’s command against false testimony, we have this:

“Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but the seventh day is a Sabbath to the Lord your God. On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the sojourner who is within your gates. For in six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy” (Exodus 20:8–11).

Here God gives a command about the Sabbath day, and a historical reason for the command. God would have been a false witness—a violation of his own commands—if what he said here about how he created the world wasn’t true. Not only did the ancient Israelites care about history—they cared about the historical reliability of their origins narrative too. There is absolutely no justification for BioLogos to ignore the Bible when it comes to knowing about the earth’s history.

Radioactive dating method

Radioactive dating is based on the measurement of unstable types of atoms (isotopes) that decay at a predictable rate. There are many different radioactive atoms, each with its own rate of decay. Old rocks require dating using isotopes that decay slowly, because faster decaying isotopes have already gone.
All three assumptions are unreliable, casting such doubt on radiometric dating that no geologist will accept a result without question.

As already stated, all ‘ages’ calculated from these dating methods are based on assumptions about the past. In the case of radiometric dating the assumptions are: (1) we know the rock’s initial conditions, (2) the rock has remained a closed system for millions/billions of years, and (3) the radioactive decay rate of the isotope in question has remained constant all that time. All three assumptions are known to be unreliable,2 casting such doubt on radiometric dating that geologists, whether evolutionist or creationist, rarely accept a result without question. Instead, part of the standard dating procedure is to check the calculated ‘age’ against what is expected, and to change the assumptions so the result makes sense. See Radioactive dating methods: Ways they make conflicting results tell the same story and The way it really is: little-known facts about radiometric dating for examples on how this works in practice.

The above claim, that “faster decaying isotopes have already gone” from older rocks, is not true. The short-lived isotope carbon-14 is consistently found in samples that are supposed to be hundreds of millions of years old, providing objective evidence against the eons of time. See for example Diamonds: a creationist’s best friend: Radiocarbon in diamonds: enemy of billions of years.

The biblical creationist literature that documents the problems with radiometric dating is voluminous (see e.g. Thousands … Not Billions, The Mythology of Modern Dating Methods, and Volume 1 and Volume 2 of the Radioisotopes and the Age of the Earth (RATE) project). This literature provides state-of-the-art research into the factors that have affected the isotope abundances in the earth crust (and in meteorites), showing that the abundances are not due to the passage of billions of years of time. For more information, see our Radiometric Dating Q and A page. Two other helpful articles are:

Extinct Radionuclides

Experiments that collide atoms at high speed have allowed scientists to determine what isotopes would have been formed in stars and supernova events. Looking for these isotopes in nature, we find only the very long-lived varieties. The short lived isotopes are “missing” because the Earth is old enough for them to have decayed away. The longest-lived missing isotopes require at least 1 billion years to decay below detectable levels.

When we read claims like this we should always ask ourselves, “Where were these scientists standing when they observed this?” If they did not observe it we know they are telling a story. It is just their subjective opinion.

Note first that the claim here simply begs the question—it assumes an old-age chronology in order to prove an old-age chronology. Why should we accept that all the isotopes in the universe formed billions of years ago in supernova events? There is in fact a decided lack of supernova remnants that should exist if the universe were billions of years old.

If we accept that God created the earth in six days some 6,000 years ago as the Bible describes, why would God have created short-lived, highly radioactive, and harmful radionuclides? And even if he did create them, it’s likely that accelerated nuclear decay during Creation Week would have neutralized such radionuclides by the time He completed His “very good” creation. For more information, see:

Dating rocks and meteorites

The oldest rocks on earth come from the interior of continents, where erosion has exposed the deep crystalline basement rock. These rocks are over 3 billion years old, with the oldest being almost 4.5 billion. Multiple meteorites have also been dated, with the oldest consistently falling close to 4.5 billion years of age.

Consistently falling close to 4.5 billion years (Ga) of age? No. There are many examples for most of the radiometric methods where dates in both terrestrial rocks and meteorites are significantly older than 4.5 Ga, even though they appear to be verified by the numerous ‘reliability criteria’ that geochronologists employ.3 As with all dating results, these dates are interpreted in such a way as to conform to the accepted secular history of the earth. One typical rationalization is to invoke open-system behaviour in the rocks. Such anomalies are never considered a problem but presumed to explain more about the history of the rock, all of which is speculation and none of which has been observed! (Note for interest that the erosion of the interior of the continents was caused by the receding waters of Noah’s Flood.) See:

Counting methods

Counting methods are based on observation of natural processes that produce a distinct layer with the passing of each year. For many tree species, slow growth in winter and rapid growth in summer produce a distinct annual tree ring. Some lakes produce annual sediment deposits called varves. Glaciers also preserve a record of annual sediment depositions between winter and summer.
All these techniques suffer from the same problem in that they ignore the effects of Noah’s Flood.

Note what is being counted—sediment layers, tree rings, and cores—not years. Before anyone can transform the number of rings and layers into years they have to make assumptions about how and when they formed. We can’t go back in time to observe. It is now clear that multiple rings and layers are regularly produced in a single year, depending on such factors as climate and hydraulic conditions.

Moreover, some of these methods are calibrated against radiometric dating methods, which is tacit admission that the methods are not reliable. And further, the calibrations introduce a calibration bias that stretches the timescale to fit the long age paradigm. All these techniques suffer from the same problem in that they ignore the effects of Noah’s Flood. That global event invalidates the assumption of one layer in one year, and affects all the methods in the same direction. As we shall see, this annuls the assumptions behind these methods and is a factor that the long-agers are not even prepared to consider.

Tree rings

As with radiometric methods, the creationist literature exploring the problems with these ‘dating methods’ is vast. See especially Rock Solid Answers and Earth’s Catastrophic Past, but for those with a more in-depth interest in specific topics, see Ice Cores and the Age of Earth, The Missoula Flood Controversy, Ancient Ice Ages or Gigantic Submarine Landslides?, Climates Before & After the Genesis Flood, Sea-Floor Sediment and the Age of the Earth.

Tree rings

The oldest living trees have more than 4,000 rings. Because annual growth varies with yearly climate differences, the ring pattern of a tree core of known age can be matched with a tree core of unknown age (perhaps taken from a beam in an ancient cliff dwelling) to extend the ring count back in time. This process, known as cross correlation, allows reliable counting back to about 12,000 rings.

There is widespread evidence that many trees, especially those with large numbers of rings, produce multiple growth rings per year depending on environmental conditions. The trees claimed to have more than 4,000 rings are bristlecone pine that grow at high elevation in dry, rocky soils in high winds, and it has been found the slow growth occurs in dry spells and rapid growth after a thunderstorm, invalidating the assumption of one pair of rings per year (see Evidence for multiple ring growth per year in Bristlecone Pines).

Further, the past climate patterns after the Flood were significantly different from what we have today, causing major uncertainty in tree ring dating. This is precisely what is inferred for the biblical Ice Age. Early in the Ice Age, the extremes between different seasons were muted and the environment was in general much wetter, which would have produced faster growth rates. Therefore, growth rings would not have been correlated with seasonal extremes, but more likely with individual storm surges.

Moreover, researchers construct long ‘chronologies’ from separate wood samples found as fallen logs on the ground. Before they can match these separate tree cores they need to know their age, and this is usually constrained by carbon dating the tree cores. This is simply a process of circular reasoning. Further, matching the tree ring pattern between separate samples is a highly subjective and flexible process. Without independent confirmation of the dates (which is best done by eyewitness testimony), this method is nothing but circular reasoning. For more information, see:


Layers with actively forming varves can be found with 100,000 or more layers. Each lake sits on complex rock layers that have their own history. Based on these modern lakes, the age of the Earth must be older than 100,000 years. In ancient lake deposits now turned to rock (such as the well-known Green River Formation), millions of layers are preserved, suggesting the Earth’s age exceeds several million years.

Varves are a favourite of long-agers, and have been since they were selectively defined as annual layers, this is merely another case of question-begging in favour of millions of years. First, there is experimental and observational evidence that demonstrates that layers form automatically when sediment composed of different sized particles is deposited from moving water. Moreover, multiple layers are deposited at the same time and they give the appearance of varves but are not annual layers. Second, for these varves to produce the sort of ‘clock’ that is here supposed we have to assume that the environmental conditions remained stable enough to produce this pattern over 100,000 years in the case of modern lakes, and for millions of years in the case of the Green River Formation. The evidence from so-called varves is consistent with the biblical timescale of thousands of years. See also:

Ice cores

Ice cores from Greenland and Antarctica preserve the longest record of snow deposition. In Greenland, the annual layering can be visibly counted down to about 50,000 layers. In Antarctica, the annual snowfall is less than Greenland, causing less thinning of the layers due to compactions, resulting in more than 400,000 measured layers.

Ice core

One problem is with the identification of the layers. Another is that multiple layers formed each year depending on environmental changes, especially in the earlier, deeper parts of the core. It’s the deeper parts of the core where the layers are increasingly difficult to identify, and this significantly affects the reliability of the ice core ‘data’. The interpretation of the cores, driven by the long-age philosophy, has many problems. They are better interpreted as forming after Noah’s Flood during the Ice Age and beyond. See:

Speleothems (cave formations)

Cave growths forming in regions where local climate varies seasonally between wet and dry or cold and warm will form an annual layer similar to tree rings. In some cases, cave formations preserve more than 200,000 annual laminations.

The description “annual” here is unobserved, subjective speculation. How could anyone alive today confirm that the layers were deposited annually for the last 200,000 years? Long-term climate changes affect the rates at which the speleothems form within caves, and the climate changed considerably after the Flood. In many places the climate was initially wetter which meant the cave decoration formed much quicker than what is observed today.

Moreover, the speleothems formed after the cave itself was carved and that involved a different process from what is observed today that is depositing the cave formations. The initial carving of the caves is explained by upwelling of hydrothermal solutions, which would have occurred during and after the Flood. These solutions would have excavated even large cave systems much more rapidly than typically assumed by long-agers. For more information see:


Some types of corals produce annual growth layers as a result of different density and seasonal incorporation of organic material. The record is clear enough in well-preserved samples to count the number of days in a year. Ancient corals preserve a record of a greater number of days per year due to a gradual slowing of Earth’s rotation.

It just so happens that creationists have published not only in the creationist literature on this topic,4 but even in the secular literature!5 Snelling summarizes the problems well:

“Much is claimed about daily growth-lines produced in many corals as they grow, and used to infer estimates of exceedingly slow coral growth rates. These growth lines form seasonal patterns, but the counting of these growth-lines in corals is quite subjective, because they are often ill-defined. Some individuals will find twice as many as others on the same sample. Furthermore, environmental factors such as water depth affect the number of growth-lines formed.”6

[Ed. note (25 January 2014): Dr. Robert Carter, a coral reef ecologist, has written a detailed critique of this argument in the Journal of Creation: ‘Ancient’ coral growth layers.]

Other dating methods

Dr Tas Walker has dealt with these methods in Dating methods and A Christian response to radiometric dating. Here we reproduce his relevant comments, which demonstrate that these methods are no more reliable than any of the other methods above.

Thermoluminescence—A technique for estimating how much time has passed since a sample was last exposed to fire or intense heat.

“Unfortunately, there are many unknowns and many assumptions need to be made, including the amount of radiation ‘stored’ in the mineral at a certain time in the past, that the change in radiation has only been affected by the radiation in the environment, that the radiation in the environment has remained constant, and that the sensitivity of the crystal to radiation has not changed. All these factors can be affected by water, heat, sunlight, the accumulation or leaching of minerals in the environment, and many other causes.” [Dating methods]

Electron Spin Resonance—In materials such as teeth, ESR provides an estimate of the time since burial.

“The calculated date is based on the same assumptions, and affected by the same uncertainties, as for TL [thermoluminescence]”. [Dating methods]

Cosmic Ray Exposure—A method for estimating how long a rock surface has been exposed to sunlight and other cosmic rays.

“Not only does this method have the problem of knowing how much of each isotope was present in the meteorite originally, but it assumes that certain isotopes were produced by exposure to cosmic rays. No matter what combination of numbers is produced from the measurements, some unknown and unseen cause can always be invoked to explain them. Very likely cosmic-ray influxes to the earth’s surface were much higher during the Ice Age than they are today, because the earth’s magnetic shield was much more leaky.” [A Christian response to radiometric dating, p. 44]

Testing for reliability

Each dating method is based on a set of assumptions about nature, but we have ways of putting each assumption to the test to determine if the dating methods are reliable.

It would be helpful if BioLogos had actually spelled out some of the assumptions they make when trying to explain what happened in the past. For the sake of clarity, here are some of those assumptions about nature:7

  • Methodological naturalism—natural cause and effect is all that matters for explaining natural history. God is not active in the picture in any sense distinguishable from natural cause and effect.
  • Actualism—natural processes (and in some cases, their rates) have basically remained the same throughout natural history. As such, there was no global Flood.
  • De facto positivism—forensic science alone is an inherently reliable witness about natural history.

These assumptions are practically indistinguishable from the assumptions secularists make for natural history—they have to be to use the same methods and get the same results. The big difference for BioLogos is that they then try to ‘attach’ secular natural history to the beginning of biblical history. However, there is no possible ‘attachment site’ for secular natural history to latch onto biblical history. Rather, there are genuine inconsistencies. For example, the biblical authors clearly interpreted Genesis 1–5 as detailing a specific historical couple—Adam and Eve—as the progenitors of all humans who had their beginning only 6,000 years ago (1 Chronicles 1:1, Mark 10:6, Luke 3:38, Acts 17:26, Romans 5:12–21, 1 Corinthians 15, Jude 14). However, there are anatomically modern human fossils that are ‘dated’ up to and beyond 100,000 years old. See Pre-Adamites, sin, death and the human fossils. To ‘harmonize’ this inconsistency we either have to dismiss the biblical account, or challenge the dates.

God’s testimony in the Bible about the past should serve as our foundation for natural history for one simple reason—He was there.

Neither is this incompatibility theologically trivial. The good news of Jesus dying for our sins and rising bodily for our justification (Romans 4:25) only makes sense in the light of a historical Adam sinning as our representative and so bringing physical and spiritual death on us all (Romans 5:12–21; 1 Corinthians 15:21–22). Of course, if Adam only came on the scene 6,000 years ago, then either those ‘pre-Adamite’ human fossils were subjected to a punishment they didn’t deserve, or sin and death did not originate with Adam. Either way, the Bible is demonstrably wrong about the reason for the gospel (for more details see our articles on Romans 5, Romans 8, and 1 Corinthians 15). And if the earth is billions of years old and humans are only a few million years old at most, then Jesus was wrong about when humans came on the scene relative to creation as a whole (Mark 10:6) (see Jesus and the age of the earth). Appealing to Jesus’ limitations in the Incarnation is no answer because the Father, who never stopped exercising His omniscience, taught Jesus what to say—especially for Jesus’ teaching ministry (John 8:28). If the earth is old, Jesus is not trustworthy and there is no reason for the gospel.

God’s testimony in the Bible about the past should serve as our foundation for natural history for one simple reason—He was there. BioLogos has no excuse for ignoring this because they claim to “believe the Bible is the inspired and authoritative word of God.” If God gives historical testimony, then it follows logically from his impeccable and omniscient nature that his testimony is inherently trustworthy. The Bible is a self-attesting axiom; forensic science is not.

BioLogos says that each dating method is tested. This is true but it is not an independent, objective test. The way it is done is that the ‘ages’ calculated from each method must agree with the billion-year evolutionary framework. All ages, whether consistent or inconsistent, are reinterpreted so they agree with the timeframe of billions of years (see Radioactive dating methods: Ways they make conflicting results tell the same story).

Radioactive dating and ocean spreading

Satellites measuring distances between continents show that they’re moving. Africa is currently moving away from North America at a rate of about 1 inch per year. New Ocean floor is created at the Mid-Atlantic Ridge as the continents move apart. This creates a testing opportunity for the reliability of radioactive dating. If the radioactive dating works reliably, the calculated rates using the radioactively determined ages should be approximately 1 inch per year—and they are!

This is an impressive claim but again we need to ask ourselves what has actually been observed. There is no reference to where this test has actually been reported in the literature, so it is an unsubstantiated assertion. For more information on the sorts of problems such claims encounter see Long-age geology or Genesis?8

This claim suggests that the rate of plate movement has remained constant for millions of years. However, the satellite data only goes back a few decades. Is it valid to extrapolate today’s rate over thousands of kilometres? This is an open question in the creationist literature (see Forum on Catastrophic Plate Tectonics). The Catastrophic Plate Tectonics model assumes the general pattern of relative age preserved in the radiometric signature of the ocean basins but shows how this can be interpreted within the biblical timeframe.

The Pacific has also experienced the same phenomenon, but with a line of islands over a tectonic hot spot that is currently building the big island of Hawaii. If created recently over a brief period, there should be little difference in the growth of coral reefs or island erosion between islands. If islands formed over millions of years, the oldest should be much more eroded and have much larger, thicker reefs—which is exactly what is observed.

The simple story of the Pacific plate passing over a hot spot has been seriously questioned by numerous secular geologists in the last 10 years (see The Hawaii Hotspot and the Bible).9,10 Second, the picture of coral reef building assumed in this story is largely out of date. It appears that rapid erosion (perhaps the result of Flood processes) created conditions for more mature reef structures in the post-Flood world. Ocean currents tend to push sediments uphill on the sides of seamounts. Moreover, any latent heat within the seamount (which was volcanically produced) would increase water cycling, and thus also nutrient cycling and reef growth along with it, because the reef structures are permeable.11 Nevertheless, the real limiting factor would be the amount of sediment available for reef building, and not so much the latent heat, because while increased latent heat may create increased reef building potential, the total of what could be done is still limited by the amount of raw building material available. Therefore, the more erosion material available, the bigger the reef structures will be compared to others over the same length of time (see Dr Robert Carter’s talk from the 2011 Creation Superconference Coral reefs and the Flood).

Combining tree rings, varves, and carbon-14

Counting tree rings and varves assumes that each layer represents 1 year. Radioactive dating assumes decay rates have been constant over time. We can put all these to the test at the same time by combining the data. When we compare the carbon-14 content of cross-correlated tree rings and varve samples from Lake Suigetsu in Japan, they confirm the validity of radioactive dating methods.

Actually the results from the different methods do not agree. The researchers produced a calibration curve for carbon-14 in order to adjust for the discrepancies between the methods. But what they are unable to correct for are factors that affect all methods, and there is one such factor which they have ignored—Noah’s Flood. This event upset the carbon balance on earth which means increasingly larger corrections are needed for carbon-14 results as we approach the date of the Flood. Laminations in lake sediments would also be affected by the Flood, with increasing numbers of laminations in the immediate post-Flood period. For more information see Long-age geology or Genesis?

Confirming radioactive dates with historic events

Radioactive dating methods applied to deposits of known age, such as ash from the 79 AD eruption of Mount Vesuvius in Italy, have yielded correct ages.
A test based on eyewitness reports is the only valid test for radiometric dating.

A test based on eyewitness reports is the only valid test for radiometric dating. It is exactly the sort of independent confirmation that radiometric dating needs. All the above ‘cross-checking’ methods compare methods that all use the same basic assumptions, so they are not independent tests of reliability. They could all be influenced by an unidentified factor, or cases of confirmation bias. Concerning this confirmation with Mount Vesuvius, Dr Tas Walker says:

“However, the article in question12 proves the opposite. The article proves the dating methods are not independent. In this case, they collected a sample of sanidine from pumice of known age based on historical eyewitness reports of the 24 August 79 AD eruption, the only way of knowing the true age of anything. Their total argon gas results gave an age of 3,300 years, which they knew was wrong because the correct answer was 1,918 years. So, using the known age they calculated the amount of ‘excess’ argon. The paper is a warning to researchers to watch out for excess argon.” [A Christian response to radiometric dating, p. 37]

Vesuvius is not the only eyewitness test that has identified excess argon as a problem. Samples from Mt St Helens in USA, Mount Ngauruhoe in New Zealand, Hawaii, and Tertiary basalt in Australia have all shown inflated ages indicating excess argon. The literature includes many examples that documented these problems.13–16 This raises the obvious question: why should we trust radiometric dates if they make such egregious errors on rocks that we know the date of? See:

Through various scientific methods, we can test, retest, and cross-examine to find the right answer.

And here is the fundamental assumption on display for how we can supposedly know that the earth is old—science will tell us the story. Science (properly done and checked, of course) always gives us a reliable answer. But does it? Consider Jesus’ miracle at Cana of turning water into wine. We could conduct chemical tests on the wine, and those tests might suggest that the wine came from grapes at a local vineyard. But because numerous people saw that the wine was water mere seconds before, any inference we make about a vineyard origin of the wine from the chemical analysis will be wrong. Therefore, we can’t always find the right answer in history through science.

The timeline in Genesis and events such as the Creation Week, the Fall, and Noah’s Flood contradict all the long-age assumptions about the past and how we can know it. This is why we need to begin with God’s eyewitness testimony when we investigate natural history—apart from what God has told us, we can’t know when He’s acted, and we won’t take that into account when we look at the forensic data. As such, we’ll be lead astray by whatever assumptions take hold of us.

And this is exactly what has happened in this poster. BioLogos has presented a very brief and misleading version of what actually goes on in these methods, presented the interpretations of these methods for chronology as ‘reliable evidence’, and proclaimed old-age chronology correct by fiat. Most of their ‘cross-checking’ methods beg the question in favour of long-age assumptions. The one independent test for long-age dating methods, historical witness, proves to be the one standard these methods fail against. Moreover, it is precisely this sort of evidence that biblical creationists invoke to invalidate long-age dating methods—the historical witness of Genesis 1–11.

God was there at the beginning and has told us about it in Genesis.

This is not to disparage the ingenious technology used to measure the isotopes and generate the raw data from which these dates are calculated. The problem is with the assumptions about what the past was like. Biblical creationists are not enemies of ‘science’. We accept the results of high-tech spectrometers. We use reports by long-agers on their field exploration. What we don’t accept are the assumptions long-agers make about the past. We don’t accept that prehistory is a given. We don’t accept that natural processes (and in some cases, their rates) have basically remained the same throughout history. We don’t accept that we can implicitly trust forensic science to ‘tell’ us about this prehistory. And we don’t believe that nature is all that matters for natural history.

Natural history is far more complex and catastrophic than long-agers grasp. They ignore the constraints that God’s eyewitness testimony places on how we should interpret the forensic data. God matters for history—both natural history and human history. God was there at the beginning and has told us about it in Genesis. God caused a global Flood, which was a one-off global watery cataclysm that has no analogue in today’s processes and rates. And forensic science must be understood in the framework that reliable testimony gives us—which has been provided in Genesis by, that’s right, God. That is how we know the age of the world, that God created in six days some 6,000 years ago.

It's hard not to believe that this group exists for the sole purpose of undermining Christian beliefs. They are keen to go out with a missionary fervor and speak about this evolutionary guff wherever they can. If they are truly Christian then shame on them. If not then pity them.

Graham D., Australia, 7 November 2012

NEWS FLASH: Most of the world's Christians believe in an old earth. The majority also believe in the science of evolution. Unlike your people, they are more concerned with the message of Christ and salvation. The way they see it, embracing science does not conflict with their salvation. I have read many articles on this website and have hardly come across anything to do with Christ's infinite love or his message, indeed all I see you doing is lying for Jesus. If something is true, then you do not need to lie to defend it. And you call yourselves Christians? For shame...

Shaun Doyle responds

It’s irrelevant what the majority believes—truth isn’t determined by a popularity contest. However, even if most of the church today believes in deep time and evolution (which is highly unlikely), then they have departed from the practically unanimous Christian belief in a young cosmos of the first 1800 years of church history in a young cosmos. And we can trace the change to a capitulation to deistic (and ultimately atheistic) geology in France and England from 1750 1850 (see St Hutton’s hagiography).

Besides, neither evolution nor deep time are ‘science’; they’re history—and bad history at that. Ignoring corroborated testimony is not a good sign (such as the scores of Flood legends from around the world that corroborate numerous details in the biblical narrative). Taking one’s speculations about the unobserved past as gospel is another bad sign (which evolutionists do by definition when they study ‘prehistory’). Ignoring the fact that the God who acts in history is also sovereign over it is another bad sign (miracles throw spanners into forensic historical works). Thinking that science can bite the theistic hand that feeds it is yet another bad sign (the Bible supplies the philosophical groundwork for why science is possible). For all the impressive-looking structures built on evolution and deep time, they still rest on foundations of sand—the assumptions make no logical sense. And for Christians who buy into them, it makes even less sense because they’re trying to mix incoherent assumptions with a worldview that’s already self-consistent and provides the only solid ground from which to do natural history.

And the accusation of ‘lying for Jesus’ makes no sense either. We believe what we write. But since we’re the heretics and pariahs of the scientific establishment, I guess any accusation will to try and shame us into submission. But then, for a worldview that makes no sense, it shouldn’t be surprising that people who hold it throw accusations that make no sense.

And are we concerned with the gospel? In this very article you complain about, we said this: “The good news of Jesus dying for our sins and rising bodily for our justification (Romans 4:25) only makes sense in the light of a historical Adam sinning as our representative and so bringing physical and spiritual death on us all (Romans 5:12–21; 1 Corinthians 15:21–22).” Our prime concern in everything we do as a ministry is the truth and integrity of the gospel message. Part of that means standing against false gospels, such as the one BioLogos promotes (Galatians 1:6–9). If you’ve only rarely found the message of Christ and salvation on our website, then I would suggest you haven’t looked very hard.

When the 'observe and extrapolate' method of dating is applied to other domains; we get, not accuracy, but disaster. Look at the 'global financial crisis'. The growth of asset values was extrapolated into the future on the expectation of continued growth; but they collapsed! So much for observe and extrapolate without any calibrating information, such as from history (or simple 'what ifs' in the case of the GFC).

Dene S., Australia, 14 October 2012

An individual who believes in an all powerful God who can create anything instantaneously, at any time He wants to, makes this individual independent, in the context of the Gospel, of any dictator or bully. This is what much of the opposition to Creationism, many control freaks, don't like, in addition to their love of sin.

It is God's power to create that matters, not WHEN and where He uses that power. The Bible tells us that there are vast numbers of angels and indicates other inhabited worlds. Whether or not these and different portions of the universe were created instantly at different times billions or millions or many thousands of years apart has no affect on what the Bible and Jesus said. The important point is they were created instantly by God's word and didn't evolve.

I think that discussions like this one about BioLogos would be simpler if we realise that Genesis 1 only clearly talks about making the planet suitable for life and then creating that life.

What is YOUNG is not the planet itself, that we call Earth, but that life on earth is young and not millions of years old etc. The 'beginning' in verse 1 is the beginning of life on earth, not of the planet itself or the universe.

Genesis 1: 8 tells us that the word, 'heavens' in this chapter refers to where fowls can fly. This could not be the universe. You cannot separate verse 1 from its context and say that that verse is talking about the vast universe in the word 'heavens'. This is basic primary school level written comprehension.

The Hebrew merism that some young earth people refer to must be subject to the context it is in, in order to get the meaning intended. Doing a Bible search on 'heaven*' can give you examples where the context dictates exactly what the author of the passage concerned has in mind, like where the birds fly or where God's throne is etc.

Similarly the earth: this is what God called the dry land (v10) when the waters were gathered. Obviously the land was wet before that. We are not told when the waters the Spirit of God was over and the land the waters covered were created. There is no, 'God said...' to create that water covered land in Genesis 1.

Perhaps this is a good point to end my contribution. The plain reading of Genesis 1 is that when God said 'let there be light' the planet earth already existed consisting of water covering land (spherical?). We are not told when this water covered land was created. It doesn't matter when it was created, but we know from John 1 that Jesus created it instantaneously by His Word. Talk of billions and millions of years is only important to the evolutionist, because he needs them for all the accidents his theory needs to get to where we are today. For the Bible believer just how old this planet and the universe is doesn’t matter. Jesus made it all and keeps them going.

Shaun Doyle responds

Please see Genesis: Bible authors believed it to be history, Jesus and the age of the earth and Did God create over billions of years? There are numerous reasons why the ‘when’ and ‘how’ of creation are just as important as the ‘who’. In fact, one of the passages we quoted in our article was Exodus 20:8–11; the relevant part says: “For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day.” It wasn’t just life on earth that was created recently; it was the whole universe (which is roughly what the merism “heaven and earth” means in Genesis 1:1, cf. Genesis 1:14–19 and the creation of the sun, moon, and stars in heaven.). Please also see our Genesis Q and A, Genesis Verse-by-Verse, and Creation Compromises pages.

On ET life, please see our Alien/UFO Q and A page, and especially our articles Did God create life on other planets? and Does denying the existence of alien life ‘limit God’?

Richard-Rafael J., Australia, 11 October 2012

Dear Dr Jonathan,

Thank you for the delightful way you edited my comments. For those (I suspect, non-Jews) who may not be aware that this is the format of Talmudic discussion—a very ancient way of Jewish debate.

JS: Dear Mr Richard-Rafael, thank you too for this very friendly discussion (and for sending me a copy of your booklet).

I will take issue with you when you say that all translations are OK, because they are very definitely not and some are even deliberately misleading

JS: Oh no, I wasn’t approving of all translations, because some are just as you say. Rather, I thought that there are some very good translations that convey the Hebrew meaning very well. In my own studies I use a few of them for comparison. I was also commending the principle of translation, so those who don’t speak Hebrew can benefit from the all-important message from the Creator in the Hebrew Bible. That would also be your aim in the book you’re working on.

—which, of course, we both understand is extremely sinful and breaks a prime mitzvotim about not adding or subtracting from the text.

JS: Definitely!

I am currently working on a new book that hopes to point out the translation errors and give the more clear meaning in English (I find English a far more complex language than Biblical Hebrew).

JS: English has had a lot of help from borrowing from other languages though.

I did look up those Yeshua references you gave in reply and whilst I don’t claim to be utterly proficient in koine Greek, I can read and write in it and I couldn’t find in the text your contention about ‘man’ being there at the beginning of Creation; which is how your comment reads—it may have simply been a misprint.


A fuller quote of Mark 10 is:

And Jesus said to them, “Because of your hardness of heart he wrote you this commandment. But from the beginning of creation, ‘God made them male and female.’ ‘Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh.’ So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”

Since Yeshua was talking about marriage, he goes back to the origin of the first human couple, which He says God made “from the beginning of creation”. The timeline in Jesus on the age of the earth should make the implication plain. He also quoting from Bereshit 1:27 and 2:24, clearly about the creation of man. Also, in the parallel account in Matthew 19, Jesus stated that “He who created them from the beginning” was the One who said: Bereshit 2:24, explicitly affirming the divine inspiration of Genesis.

As we show in another article, the passage is clearly talking about man being from the beginning of creation not just the beginning of marriage. And in my book Refuting Compromise, I discuss this passage, including the Koine Greek (I am impressed that you are good at this as well):

For example, explaining that the doctrine of marriage is founded upon the creation of marriage, Jesus quotes from Genesis 1:27 and 2:25 (Matthew 19:3–6, Mark 10:6–9). In particular, Jesus says in Mark 10:6:

‘But from the beginning of creation, God made them male and female.’

This makes sense only if Jesus affirmed that Genesis was intended to be interpreted straightforwardly. I.e. where the earth was created about 4,000 years before He spoke those words, and Adam and Eve were created on Day 6, which, on the scale of 4,000 years, is almost indistinguishable from the beginning (0.0004% away on that number line). This contrasts with the usual evolutionary view that we swung down from the trees a few million years ago, and even more with Ross’s view that Adam and Eve were created 10–60 thousand years ago.

Some would wishfully claim that it simply means ‘from the beginning of “their” creation’. But this makes little sense―of course they were male and female from the beginning of their own creation. What else would they have been―hermaphrodites? No, the context is clear that Jesus is pointing out God’s plan right from the beginning of the creation. The Greek also supports the reading ‘from beginning of creation’ (ἀπὸ δὲ ἀρχῆς κτίσεως, apo de archēs ktiseōs). This is supported by other passages where this phrase is clearly used of the whole creation.

Mark 13:19 “For in those days there will be such tribulation as has not been from the beginning of the creation which God created until now, and never will be.”

2 Peter 3:4 “[Scoffers say] ‘Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of the creation.’”

These two passages have the Greek phrase ἀπ’ ἀρχῆς κτίσεως (ap archēs ktiseōs), which is identical to that in Mark 10:6―it makes no difference to the point that these lack the preposition de (which is a new topic marker, or sometimes ‘but’) and have the ap instead of apo, since the former is used before a vowel (archēs) and the latter before a consonant (de). Further, both these passages reinforce the teaching that mankind has been around about as long as creation itself.

Lastly, and this came as a bit of a shock to me as well, I looked up your details on this website and that video of you and my wife saw it as well, and it was she who remarked “Good G-D, that man looks like a younger version of you, he could be your son!”

JS: I am honoured by the comparison.

I know that the family mythology says that on father’s side they were Dutch, French and Germans who immigrated to England after Jews were readmitted to England by Oliver Cromwell in ca. 1675. What was your mother’s maiden name and was she Jewish? Sorry all you non-Jews our there, We Yiddishers (what Askenasim Jews often call each other) are a nosy lot, but it’s done in love and good humour.

JS: Indeed so. My ancestry is complex as well. My name צרפתי is Sephardic (meaning “Frenchman” as you no doubt know), and some people with this name were quite influential, for what it’s worth (and I have no idea of exact relations). Dr Samuel Sarfati came from France, as expected, but moved to Rome and became leader of the Jewish community there and personal physician to Popes Alexander VI and Julius II, and his son Dr Joseph Sarfati was physician to Pope Clement VII (16 century). My great great grandfather was Jacob Joseph (paternal grandmother’s side), the first Jewish settler in New Zealand; my old university Victoria has a scholarship in his name. But I’d better not take over the comments page of my colleagues’ article too much ;)

All special blessings to you for Shimat Torah (now is the time in the Jewish calendar when the Parashah (the weekly scripture reading) is the Creation account of Bereish (Genesis) 1:1–6:8.

This should be a special time for your ‘ministry’

Love and Blessings,


JS: The same to you, and all the best to you too for Shimat Torah.
Don S., United States, 10 October 2012

In the August 2012 issue of CMI's Journal of Creation, a 2-part article proposed a new Flood model which could explain why fossil corals do seem to record shorter days before the Flood. The proposed explanation is that before the Flood the Earth was cool and thus smaller and thus spun faster, and thus there were more days in a year before the Flood.

Tas Walker responds

Hi Don,

Indeed it is possible that the earth's rotation was different in the past before the Flood. The Journal paper you refer to suggests the rotation was faster in the past becasuse the earth was cooler. Another possibility is that the rotation was slower because it was undifferentiated.

The Nature paper by Wells about the corals claims a gradual slowing down of the earth over hundreds of millions of years from 424 days in the Devonian to 371 in the Cretaceous. Within a Flood model we would not expect a gradual reduction in coral rings becasue the fossil record was deposited within the Flood year (more likely within the first half of the Flood year). There would be no time for corals to grow with different number of rings. Rather we would expect an abrupt reduction between the pre-Flood corals and the post-Flood corals. That is, of course, if indeed the corals are recording a change in day length.

Geoff C. W., Australia, 7 October 2012

Reminds one of the factory foreman who used to set his watch by the large clock in the watchmaker's store as he passed by on his way to work every morning. He needed accurate time, as he had to sound the knock-off siren to signal the end of work every evening.

One day, in conversation with the watchmaker, he discovered that the watchmaker set his clock every evening by the knock-off siren at the factory.

You're only as good as your assumptions.

john C., United States, 6 October 2012

There is only one way to reliably know the age of anything and that is by eyewitness testimony, on the basis of their written records.

Even with written records your still assuming that the writer did not A:lie or B:make a mistake.

Tas Walker responds

Hi John,

That is correct, and the reason the Bible requires truth be established on the testimony of two or three witnesses. In fact, the whole of the scientific endeavour rests on eyewitness testimony and why experiments and observations are carefully documented so they can be independently repeated.

Nick B., Canada, 6 October 2012

The Roman Catholic Church made the same big mistake by adopting the scientific beliefs of the day regarding Earth's place in the universe replacing what the Bible teaches. Science, or man's present level of knowledge and understanding, is always changing (not the Bible). When Galileo's new observations forced the science of the day to be questioned, he was persecuted by the Roman Catholic Church for going against church dogma when in fact it was simply a case of new and better scientific thinking replacing old and now disproven scientific beliefs. If the Roman Catholic Church, like the Orthodox Church, trusted in the authority and reliablity of the Bible as the learned did for over 2000 years and not place its faith in man's fallible scientific thinking of the day, our generation would probably never have heard of Galileo or make distinctions between scientific truths and Biblical truths when in fact there are no differences!

Tas Walker responds

Indeed, see The Galileo twist.

JAMES S., United States, 5 October 2012

The acceptance of so many variables that can't be known without presupposing uniformity is staggering. And if we believe that God's Word is special revelation then we have at least two recorded events that have drastically altered what we call the natural world; God's curse of the earth and the flood. To draw scientific conclusions from observing the universe now without considering these two recorded events is sheer folly. I'm aiming this comment at those Christians who believe that the cosmos is the 67th book of the Bible. Whenever you put general revelation or nature as equal with special revelation or scripture you end up with man's interpretation overriding God's clearly spoken word. And we know the result of this kind of thinking.

Robin B., New Zealand, 5 October 2012

I work in soil science in the North Island of New Zealand in a region where many of our soils originate from various historical volcanic eruptions, including the Taupo eruption around 1800 years ago which is probably the biggest volcanic eruption in the world over the past few thousand years. These pumice soils are relatively unweathered, and have shallow top-soils, compared to much older eruptions where the soils are much more weathered and ancient. Although it is probably of no interest to some reading this post because it violates their preciously held beliefs, for those with an enquiring mind, I suggest if ever in New Zealand to drive down Ashpit Road on the way to Lake Rerewhakaietu near Rotorua, where a road cutting exposes various layers of volcanic eruptions and A horizons that built up over the centuries and millenia after each eruption going back over 30,000 years. Although it is nice and fanciful to try and interpret evidence within the Biblical Genesis paradigm, the evidence I see in my field of expertise fits within the Biologos paradigm of a much older planet. Belief in an old age Earth does not violate my Christian faith, and theological arguments to the contrary are just that......theological and not scientific. To try and squeeze science within a literal Genesis paradigm is largely dishonest.

Tas Walker responds

Hi Robin,

Thanks for your feedback. Remember though that your soil arguments for long ages have already been answered at Soil Formation Challenge.

Richard-Rafael J., Australia, 5 October 2012

R-RJ: Thank you for your latest production.

Jonathan Sarfati responds: You are very welcome.

R-RJ: May I add a comment from a non-Christian?

JS: Certainly you may.

R-RJ: I am an elderly and (fairly) observant Jew who has taught Biblical Hebrew (and Aramaic) to Jews and non-Jews for many years. I recently had published A Complete Biblical Hebrew Root and Significant Word Dictionary (Hebrew to English) which I’m told was the first complete Hebrew root dictionary (in Hebrew and English)produced in more than 100 years.

JS: That is a great achievement indeed.

R-RJ: Faithful Jews are, of course, fervent Creationists and everyday in our prayers we bless HaShem (G-D) as “Creator of the Universe”. I think we can safely assume that Yeshua (Jesus) had a Jewish education and remained a faithful Jew all his life—so here’s my point.

JS: As a Jewish Christian myself, I am happy to affirm His Jewishness strongly, and am disappointed in fellow Christians who try to gentilize Him. And in keeping with His Jewishness, He affirmed the Creation account in Genesis (citing Genesis 1:24 and 2:27) as teaching that man was there “from the beginning of creation” and many of the other Hebrew Bible events much mocked by Skeptics.

R-RJ: The whole Creation ‘story’ in Genesis (known to Jews as Beresheit, the first ‘Book of Moses’)is told in 31 Hebrew sentences containing 365 words(!). If one doesn’t read Hebrew and relies only on a venacular translation—and I’ve yet to find a truly accurate English translation—one misses so much and can come to erroneous conclusions.

JS: There is nothing wrong with the translations; rather, anyone who denies their plain meaning doesn’t do so because of the Hebrew text, but from outside ideas imposed on the text. It would be fairly safe to assume that nothing in your own dictionary would give any hint of Schroeder’s ideas.

R-RJ: Are you aware that faithful Jews have always understood that the Torah has two clocks, one that recognizes a world which is about 5,700 years old and a six day creation that, from the human perspective is about 15 billion years old.

JS: Are you aware that Josephus and Ibn Ezra and the Talmud would disagree with you? ;) Plenty of Orthodox rabbis have no doubt that six days mean six days. The only way you get the 15 billion figure is by swallowing the false big bang cosmology, which even many secular cosmologists are abandoning.

R-RJ: Jews count the date of the world not from the creation of the Universe, but from the creation of the Adam’s nephesha (soul).

JS: Which was on Day 6 after the creation of the world.

R-RJ: Are you aware of the work of (Rabbi) Dr Gerald Schroeder—double PhD in Nuclear Physics; Earth and Planetary Sciences, MIT professor and author of Genesis and the Big Bang, The Science of God, The Hidden Face of God, et al.?

JS: Yes indeed, as shown by Response to a Gerald Schroeder fan and Gerald Schroeder and his new variation on the “day-age” theory Part 1 and Part 2? ;)

R-RJ: Many atheistic ‘scientists’ have attacked Dr Gerald because they (falsely) claim the G-D has no place in science and Dr Gerald hammers home to them that G-D is the Creator and without G-D there is no ‘science’.

JS: A point we make in The biblical roots of modern science and Why does science work at all? Medieval and modern Europe developed science largely because of the insights in the Hebrew Scriptures such as a divine Lawmaker. It is largely thanks to the church that the divinely inspired Hebrew Bible was widely disseminated throughout Europe then the rest of the world.

R-RJ: I would like to send you an article I wrote some years ago exlaining the faithful Jews’ position if you’d care to read it.

JS: Depends what “faithful Jew” means. I consider myself a faithful Jew (my name is Hebrew as you no doubt recognize, and my father’s family only barely survived Nazi occupation of France), because I believe that Yeshua is the fulfilment of the Hebrew Bible prophecies of the Messiah. And on a personal level, I staunchly support the Jewish State of Israel. My great uncle was the first New Zealander to settle in the Holy Land, as long ago as 1928—Dr Edward Joseph, who became a famous surgeon at Hadassah Hospital in Jerusalem. Many of his descendants live in Israel to this day.

R-RJ: Love and Blessing, R-R Joachim

JS: You too,

Jonathan Sarfati, Ph.D., F.M.

Paul N., New Zealand, 5 October 2012

I'll stand by what I am saying here - seen to many people's faith badly affected by the kind of propaganda you are trying to counter. And I am afraid that the people who write the compromises you are opposing, all too often consciously know the fudges that they are making. And disgustingly for $ome of them it i$ for the mo$t $imple of rea$on$.

Keep up the good work!

Again proves that just tacking the word Christian on to something does not automatically make it Christian at all.

Either a person who wishes to publicly teach or inform others, does trust and fully accept the truths of the Lord Jesus Christ - and what the Holy Spirit has unambiguously declared in Scripture, and is a follower of the Lord Jesus - or they do not - and are not.

A person may not say, 'I believe in Jesus but don't accept His Lordship, and reserve the humanistic intellectual right to publicly disagree and twist what the Lord says'.

On these points it is simply not a work of the enquiring intellect, it is all a direct work of the Evil One.

It is no longer a personal matter of faith. It then is a matter of false public teaching.

It is time to stop pulling punches and directly declare that people who so decry the very words of our Lord Jesus, and destroy people's confidence in the Holy Spirit's inspiration of the Scripture, are not at all Christians whatever they may see themselves as.

Its that straight forward. And must be called in by believers for what it is now.

It all truly is in the area of absolutes, and the very foundations, of what it is to be a Christian.

And as God's holy nation set apart to Him we should not try and falsely pander to any kind of it, or allow room for it any more.

Encourage the weak, help the timid, but stop the mouths of gainsayers!

Jesse M., United States, 4 October 2012

@Curtis C., you would appreciate this. I remember the testimony of an agnostic who, through looking at the scientific evidence, came to the conclusion that there must be a creator, but was not sure which one. To solve this issue, she looked at the religious texts of 12 different religions (including Christianity) and examined any scientific claims in them. She found that the Bible was the ONLY one that has no scientific errors. From that, she concluded that only the Bible could be inspired, and eventually came to Christ.

KD J., Korea, Republic of, 4 October 2012

The words from BioLogos fulfils the words in New Testment, 2 Peter, Chapter 3. "3. Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, 5. For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:

6. Whereby the world that then was, being overflowed with water, perished: 16. As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction." When I checked these words with the statements of BioLogos, I was very astonished because of the exact same words Peter prophesied 2000 years ago.

What amazes me that they can't see is that nothing in their arguments actually -supports- belief. Anybody not raised in a Christian setting reading this poster would logically conclude that atheism is true. If they get down to the little slogan at the end that claims Biologos is harmonizing 'science' with 'conservative Christian faith', I think their reaction would likely be a lot like Dawkins' reaction to similar arguments. They would instantly recognize that the poster did not really attempt to explain how the Bible fits with these claims or predicts them.

I had a supporter of Biologos recently tell me that he believes that science can be done by leaving out religious beliefs (therefore the secularists' claim that Earth is billions of years old is to be blindly trusted). But really, what they are doing is concocting a made-up religious belief that the idea of the Bible's truth is not testable; assuming God did not act miraculously in creation (even though he said he did) therefore science that shares that blind assumption will reach accurate conclusions. Their message is "it doesn't look like God created; it looks like atheistic evolution is true... but believe anyways!"

And of course, to purposefully not look very closely at that science to see that it actually looks young when looked at honestly, ironically.

How much stronger the argument that creationists use, when they can accurately point to evidences that science confirms the Bible! The truth is God made some predictions that we -should- be able to test, and when scientists do test them enough to reach sound conclusions, the results always confirm the Bible. :) This provides a positive reason to be convinced that God is real, the Bible is his Word, and faith in Jesus saves. ^_^

This is why I am saved today. If God's word was not testable, I could not have accepted Jesus as my Savior. You could believe -anything- if it wasn't testable. We can never know, of course, for sure based purely on science what happened in history -- there's always a leap of faith -- but science that does test biblical assumptions reaches consistent and logical conclusions.

I can understand it because I was once an atheist and a naturalist. However, doesn't it strike you as odd that secularists are extremely creative in their interpretations and imaginations to bend the evidence into their worldview and paradigm, and then oddly enough insist that their conclusions are facts and everyone else is silly. It always amazes me. Sadly many Christians butt into this madness and are unable to see the folly and somehow think they are being scholarly and sophisticated.

It is a pity that they didn't include the many unformitarian methods that give CONTRARY ages, such as saltiness of seawater, carbon 14 in diamonds, helium in biotite.

They make a song and dance about their methods agreeing. Of course they agree if you select the ones that agree and exclude others that disagree!

Shaun Doyle responds

Great point. There are many evidences, even using similar assumptions (without considering them as absolutely reliable) that strongly suggest that the earth and the universe are much younger than the standard billions-of-years story. On which, please see Age of the earth and ‘Young’ age of the Earth & Universe Q&A. We have added a small update to this effect into the paragraph of the article beginning, "The methods described in this poster ..."

Excellent point by point refutation of the claims of "BioLogos" and a critical look at their underlying assumptions. Indeed their claim to be "evangelical" and "conservative" seems amiss when the agenda of their stance is shown to uphold "evolution" rather "than the authority and reliability of scripture". Joshua 23:6-9, Joshua 24:14-15.

In response to "BioLogos and the age of the earth: Pushing an anti-biblical doctrine" I must say I am very impressed. It's good for science (even if people disagree with your conclusions - which I do not) to be always questioning the assumptions.

If a man declares "I weigh X kilograms" and then calibrates his scales according to his assumption, it's likely that he'll get faulty measurements when he weighs himself and other objects. Even if other measurements he makes are consistent with what he gets from his scales, they're still suspect because of the assumptions made. Good on you.

If the people at Biologos are so confident they believe the Universe is billions of years old, then what was God doing for all that time? Are they proposing God ignored the Universe for billions of years and then came back some 2,000 years ago, once evolution has taken its course, to offer us salvation through the crucifixion and resurrection of Jesus Christ? Am I the only one who can see that such an idea is ridiculous? Besides, the scriptures refute such a notion several times. So, Biologos does not really believe in the Biblical God but have opted to believe in another god, more aligned with the likes of the ancient Greeks and Romans.
