How old is the earth?

From Refuting Evolution, a handbook for students, parents, and teachers countering the latest arguments for evolution

by , Ph.D., F.M.

First published in Refuting Evolution, Chapter 8

Evolutionists fallaciously think that billions of years of time makes particles-to-people evolution possible. So Teaching about Evolution and the Nature of Science presents what it claims is evidence for vast time spans. This is graphically illustrated in a chart on pages 36–37: man’s existence is in such a tiny segment at the end of a 5-billion-year time-line that it has to be diagrammatically magnified twice to show up.

On the other hand, basing one’s ideas on the Bible gives a very different picture. The Bible states that man was made six days after creation, about 6,000 years ago. So a time-line of the world constructed on biblical data would have man almost at the beginning, not the end. If we took the same 15-inch (39 cm) time-line as does Teaching about Evolution to represent the biblical history of the earth, man would be about 1/1000 of a mm away from the beginning! Also, Christians, by definition, take the statements of Jesus Christ seriously. He said: ‘But from the beginning of the creation God made them male and female’ (Mark 10:6), which would make sense with the proposed biblical time-line, but is diametrically opposed to the Teaching about Evolution time-line.

This chapter analyzes rock formation and dating methods in terms of what these two competing models would predict.

The rocks

The vast thicknesses of sedimentary rocks around the world are commonly used as evidence for vast age. First, Teaching about Evolution gives a useful definition on page 33:

Sedimentary rocks are formed when solid materials carried by wind and water accumulate in layers and then are compressed by overlying deposits. Sedimentary rocks sometimes contain fossils formed from the parts of organisms deposited along with other solid materials.

The ‘deep time’ indoctrination comes with the statement ‘often reaching great thicknesses over long periods of time.’ However, this goes beyond the evidence. Great thicknesses could conceivably be produced either by a little water over long periods, or a lot of water over short periods. We have already discussed how different biases can result in different interpretations of the same data, in this case the rock layers. It is a philosophical decision, not a scientific one, to prefer the former interpretation. Because sedimentation usually occurs slowly today, it is assumed that it must have always occurred slowly. If so, then the rock layers must have formed over vast ages. The philosophy that processes have always occurred at roughly constant rates (‘the present is the key to the past’) is often called uniformitarianism.

Uniformitarianism was defined this way in my own university geology class in 1983, and was contrasted with catastrophism. But more recently, the word ‘uniformitarianism’ has been applied in other contexts to mean also constancy of natural laws, sometimes called ‘methodological uniformitarianism,’ as opposed to what some have called ‘substantive uniformitarianism.’

It should also be pointed out that uniformitarian geologists have long allowed for the occasional (localized) catastrophic event. However, modern historical geology grew out of this general ‘slow and gradual’ principle, which is still the predominantly preferred framework of explanation for any geological formation. Nevertheless, the evidence for catastrophic formation is so pervasive that there is a growing body of neo-catastrophists. But because of their naturalistic bias, they prefer, of course, to reject the explanation of the Genesis (global) flood.

However, a cataclysmic globe-covering (and fossil-forming) flood would have eroded huge quantities of sediment, and deposited them elsewhere. Many organisms would have been buried very quickly and fossilized.

Also, recent catastrophes show that violent events like the flood described in Genesis could form many rock layers very quickly. The Mount St. Helens eruption in Washington state produced 25 feet (7.6 meters) of finely layered sediment in a single afternoon!1 And a rapidly pumped sand slurry was observed to deposit 3 to 4 feet (about 1 meter) of fine layers on a beach over an area the size of a football field. Sedimentation experiments by the creationist Guy Berthault, sometimes working with non-creationists, have shown that fine layers can form by a self-sorting mechanism during the settling of differently sized particles.2,3

In one of Berthault’s experiments, finely layered sandstone and diatomite rocks were broken into their constituent particles, and allowed to settle under running water at various speeds. It was found that the same layer thicknesses were reproduced, regardless of flow rate. This suggests that the original rock was produced by a similar self-sorting mechanism, followed by cementing of the particles together.4The journal Nature reported similar experiments by evolutionists a decade after Berthault’s first experiments.5

So when we start from the bias that the Bible is God’s Word and is thus true, we can derive reasonable interpretations of the data. Not that every problem has been solved, but many of them have been.

Conversely, how does the ‘slow and gradual’ explanation fare? Think how long dead organisms normally last. Scavengers and rotting normally remove all traces within weeks. Dead jellyfish normally melt away in days. Yet Teaching about Evolution has a photo of a fossil jellyfish on page 36. It clearly couldn’t have been buried slowly, but must have been buried quickly by sediments carried by water. This water would also have contained dissolved minerals, which would have caused the sediments to have been cemented together, and so hardened quickly.

The booklet Stones and Bones6 shows other fossils that must have formed rapidly. One is a 7-foot (2m) long ichthyosaur (extinct fish-shaped marine reptile) fossilized while giving birth. Another is a fish fossilized in the middle of its lunch. And there is a vertical tree trunk that penetrates several rock layers (hence the term polystrate fossil). If the upper sedimentary layers really took millions or even hundreds of years to form, then the top of the tree trunk would have rotted away.

Ironically, NASA scientists accept that there have been ‘catastrophic floods’ on Mars7 that carved out canyons8 although no liquid water is present today. But they deny that a global flood happened on earth, where there is enough water to cover the whole planet to a depth of 1.7 miles (2.7 km) if it were completely uniform, and even now covers 71 percent of the earth’s surface! If it weren’t for the fact that the Bible teaches it, they probably wouldn’t have any problem with a global flood on earth. This demonstrates again how the biases of scientists affect their interpretation of the evidence.

Radiometric dating

As shown above, the evidence from the geological record is consistent with catastrophes, and there are many features that are hard to explain by slow and gradual processes. However, evolutionists point to dating methods that allegedly support deep time. The best known is radiometric dating. This is accurately described on page 35 of Teaching about Evolution:

Some elements, such as uranium, undergo radioactive decay to produce other elements. By measuring the quantities of radioactive elements and the elements into which they decay in rocks, geologists can determine how much time has elapsed since the rock has cooled from an initially molten state.

However, the deep time ‘determination’ is an interpretation; the actual scientific data are isotope ratios. Each chemical element usually has several different forms, or isotopes, which have different masses. There are other possible interpretations, depending on the assumptions. This can be illustrated with an hourglass. When it is up-ended, sand flows from the top container to the bottom one at a rate that can be measured. If we observe an hourglass with the sand still flowing, we can determine how long ago it was up-ended from the quantities of sand in both containers and the flow rate. Or can we? First, we must assume three things:

Hourglass illustration

An hourglass ‘clock’ tells us the elapsed time by comparing the amount of sand in the top bowl (‘Parent’) with the amount in the bottom bowl (‘Daughter’).

  1. We know the quantities of sand in both containers at the start. Normally, an hourglass is up-ended when the top container is empty. But if this were not so, then it would take less time for the sand to fill the new bottom container to a particular level.
  2. The rate has stayed constant. For example, if the sand had become damp recently, it would flow more slowly now than in the past. If the flow were greater in the past, it would take less time for the sand to reach a certain level than it would if the sand had always flowed at the present rate.
  3. The system has remained closed. That is, no sand has been added or removed from either container. However, suppose that, without your knowledge, sand had been added to the bottom container, or removed from the top container. Then if you calculated the time since the last up-ending by measuring the sand in both containers, it would be longer than the actual time.

Teaching about Evolution addresses assumption 2:

For example, it requires that the rate of radioactive decay is constant over time and is not influenced by such factors as temperature and pressure—conclusions supported by extensive research in physics.

It is true that in today’s world, radioactive decay rates seem constant, and are unaffected by heat or pressure. However, we have tested decay rates for only about 100 years, so we can’t be sure that they were constant over the alleged billions of years. Physicist Dr Russell Humphreys suggests that decay rates were faster during creation week, and have remained constant since then. There is some basis for this, for example radiohalo analysis, but it is still tentative.

Teaching about Evolution also addresses assumption 3:

It also assumes that the rocks being analyzed have not been altered over time by migration of atoms in or out of the rocks, which requires detailed information from both the geologic and chemical sciences.

This is a huge assumption. Potassium and uranium, both common parent elements, are easily dissolved in water, so could be leached out of rocks. Argon, produced by decay from potassium, is a gas, so moves quite readily.


There are many examples where the dating methods give ‘dates’ that are wrong for rocks of known historical age. One example is rock from a dacite lava dome at Mount St Helens volcano. Although we know the rock was formed in 1986, the rock was ‘dated’ by the potassium-argon (K-Ar) method as 0.35 ± 0.05 million years old.9 Another example is K-Ar ‘dating’ of five andesite lava flows from Mt Ngauruhoe in New Zealand. The ‘dates’ ranged from < 0.27 to 3.5 million years—but one lava flow occurred in 1949, three in 1954, and one in 1975!

What happened was that excess radiogenic argon (40Ar*) from the magma (molten rock) was retained in the rock when it solidified. The secular scientific literature also lists many examples of excess 40Ar* causing ‘dates’ of millions of years in rocks of known historical age. This excess appears to have come from the upper mantle, below the earth’s crust. This is consistent with a young world—the argon has had too little time to escape.10

  • If excess 40Ar* can cause exaggerated dates for rocks of known age, then why should we trust the method for rocks of unknown age?

Another problem is the conflicting dates between different methods. If two methods disagree, then at least one of them must be wrong. For example, in Australia, some wood was buried by a basalt lava flow, as can be seen from the charring. The wood was ‘dated’ by radiocarbon (14C) analysis at about 45,000 years old, but the basalt was ‘dated’ by the K-Ar method at c. 45 million years old!11 Other fossil wood from Upper Permian rock layers has been found with 14C still present. Detectable 14C would have all disintegrated if the wood were really older than 50,000 years, let alone the 250 million years that evolutionists assign to these Upper Permian rock layers.12[Update: see also Radiometric dating breakthroughs for more examples of 14C in coal and diamonds, allegedly millions of years old.]

According to the Bible’s chronology, great age cannot be the true cause of the observed isotope ratios. Anomalies like the above are good supporting evidence, but we are not yet sure of the true cause in all cases. A group of creationist Ph.D. geologists and physicists from theCreation Research Society and the Institute for Creation Research are currently working on this topic. Their aim is to find out the precise geochemical and/or geophysical causes of the observed isotope ratios.13 One promising lead is questioning Assumption 1—the initial conditions are not what the evolutionists think, but are affected, for example, by the chemistry of the rock that melted to form the magma. [Update: it turned out that Assumption 2 was the most vulnerable, with strong evidence that decay rates were much faster in the past.  See the results of their experiments in Radioisotopes & the Age of the Earth volumes 1 and 2.]

Evidence for a young world

Actually, 90 percent of the methods that have been used to estimate the age of the earth point to an age far less than the billions of years asserted by evolutionists. A few of them:

  • Red blood cells and hemoglobin have been found in some (unfossilized!) dinosaur bone. But these could not last more than a few thousand years—certainly not the 65 million years from when evolutionists think the last dinosaur lived.14
  • The earth’s magnetic field has been decaying so fast that it couldn’t be more than about 10,000 years old. Rapid reversals during the flood year and fluctuations shortly after just caused the field energy to drop even faster.15
  • Helium is pouring into the atmosphere from radioactive decay, but not much is escaping. But the total amount in the atmosphere is only 1/2000 of that expected if the atmosphere were really billions of years old. This helium originally escaped from rocks. This happens quite fast, yet so much helium is still in some rocks that it couldn’t have had time to escape—certainly not billions of years.16
  • A supernova is an explosion of a massive star—the explosion is so bright that it briefly outshines the rest of the galaxy. The supernova remnants (SNRs) should keep expanding for hundreds of thousands of years, according to the physical equations. Yet there are no very old, widely expanded (Stage 3) SNRs, and few moderately old (Stage 2) ones in our galaxy, the Milky Way, or in its satellite galaxies, the Magellanic clouds. This is just what we would expect if these galaxies had not existed long enough for wide expansion.17
  • The moon is slowly receding from earth at about 1½ inches (4 cm) per year, and the rate would have been greater in the past. But even if the moon had started receding from being in contact with the earth, it would have taken only 1.37 billion years to reach its present distance. This gives a maximum possible age of the moon—not the actual age. This is far too young for evolution (and much younger than the radiometric ‘dates’ assigned to moon rocks).18
  • Salt is pouring into the sea much faster than it is escaping. The sea is not nearly salty enough for this to have been happening for billions of years. Even granting generous assumptions to evolutionists, the seas could not be more than 62 million years old—far younger than the billions of years believed by evolutionists. Again, this indicates a maximum age, not the actual age.19

A number of other processes inconsistent with billions of years are given in the booklet Evidence for a Young World, by Dr Russell Humphreys.

Creationists admit that they can’t prove the age of the earth using a particular scientific method. They realize that all science is tentative because we do not have all the data, especially when dealing with the past. This is true of both creationist and evolutionist scientific arguments—evolutionists have had to abandon many ‘proofs’ for evolution as well. For example, the atheistic evolutionist W.B. Provine admits: ‘Most of what I learned of the field in graduate (1964–68) school is either wrong or significantly changed.’20 Creationists understand the limitations of these dating methods better than evolutionists who claim that they can use certain present processes to ‘prove’ that the earth is billions of years old. In reality, all age-dating methods, including those which point to a young earth, rely on unprovable assumptions.

Creationists ultimately date the earth using the chronology of the Bible. This is because they believe that this is an accurate eyewitness account of world history, which can be shown to be consistent with much data.

Addendum: John Woodmorappe has published a detailed study demonstrating the fallacy of radiometric ‘dating,’ including the ‘high-tech’ isochron method: The Mythology of Modern Dating Methods (El Cajon, CA: Institute for Creation Research, 1999).

Bible texts are referenced which indicate that creation took place about 6000 years ago. Massive theological problems associated with adding 'millions of years' to the Bible are also summarized.

How old is the earth? Evolution says the earth is 4.54 billion years old and the universe 13.77 billion years old. The Bible says it is about 6000 years old. What does science say?
