The Bible talks in a number of places about ‘giants’ in the land of Canaan, and the pre-Flood Nephilim (please see Return of the Nephilim?). We have recently received reports of a ‘giant footprint’ about 1.2 m (4 ft) long in granite near Mpuluzi, near the Swaziland border in the Mpumalanga province in north-eastern South Africa. In a recent video posted on Youtube,2 one Michael Tellinger, styled as a ‘scientist’, researcher, author,3 depicted this footprint as evidence of ancient giants that walked the land. While we may not give much credence to Tellinger’s far-fetched conjectures on the history of these giants, does this print still provide positive evidence for ‘ancient giants’?
Weathering the ‘footprint’ hype
Perhaps the most important fact about this ‘footprint’ is that it is stated to be in granite. Every geologist (or even field geological observer)—creationist or evolutionist—agrees that granite is not a sedimentary rock, such as the ‘mud’ Tellinger refers to as having been ‘pushed up’. Granite is an igneous rock, which becomes solid as crystals form when a previously very hot molten magma (around 800°C) cools down. It is difficult to imagine any sort of footprint, or fossil for that matter, surviving such a process. It is even more difficult to contemplate what would happen to the ‘giant’ who was going for a stroll barefoot in this igneous material that being soft, was still blazing hot! Remember too that granite does not form on the surface of the earth but deep underground in large plutons. So one can really rule out this giant-footprint idea without going much further. But since this is already doing the ‘internet rounds’, and someone is bound to ask how this shape could form if it were not a print, we can look at some of the other features that enable an ‘offsite’ dismissal of the claim with an even greater overall degree of confidence.
Figure 2. The ‘toes’ of the ‘footprint’. These are likely mini-tafoni produced because of the ledge of more resistant rock providing favourable conditions for tafone formation. Width of image is approx. 0.7 m (2.2 ft).
When exposed on the surface, granite not uncommonly erodes in ways that can result in some remarkable shapes This website features photos of the famous Remarkable Rocks on South Australia’s Kangaroo island. And here is a photo of a similar type of cavernous weathering, in Sardinia. The rock face with the alleged footprint has numerous such small cave-like features called tafoni—singular tafone— (Figure 1 — pic of the rock face), which are common weathering features in granite (See this photo for another such example). In fact the overhanging ledge above the ‘toes’ of the ‘footprint’ is most likely a more resistant portion of the rock which has favoured the mini-tafoni formation (Figure 2 — close up of the ‘toes’).
In the Tellinger video documenting this ‘footprint’, on the way up the hill to the formation you can see lots of granite ‘flakes’ that have broken off the larger granite body through weathering. It is not uncommon for rocks to crack and flake in a shape that can look vaguely like a footprint. There are also numerous little pools with water and vegetation draining a trickle of water, often in interconnected sequence all along the slopes.
If this were a giant footprint, the creature that made it certainly would not qualify as ever having been part of the gene pool of the human race.
In short, the single foot-like shape is nowhere near as unlikely to have occurred by random, natural processes as it might appear at first.
Digits 2 to 4 are virtually of the same length, which is unusual in humans but consistent with the ledge controlling tafone formation. The ‘toe’ tafoni may have also been enhanced by human chiselling attempting to make a structure already resembling a human print look even more so, but more investigation on site would be needed to demonstrate this.
If all of that were not enough, the position of the ‘footprint’ doesn’t favour it being a genuine footprint either. The ‘footprint’ is found on an essentially vertical outcrop of granite, and as such would need to be turned and pushed up by tectonic movement, which the video also claims has happened. However, the granite looks like an undisturbed pluton and does not have any indications of having been tilted up because it has no signs of metamorphism (recrystallization of pre-existing rock caused by heat and/or pressure). Granite that has been tilted and metamorphosed should show signs such as banding or layering. The movement of the rock would move the minerals into darker and lighter bands of more mafic and more felsic layers respectively. It seems that not only would the ‘giant’ need to be able to walk on molten magma, but he would have to be able to walk up the side of a wall of molten magma underground!
Importantly, too, all we have is a single ‘footprint’, not a trackway. In fact, even if this print had been in sedimentary rock, and was only a little bit enlarged, an isolated footprint impression is one of the most difficult of fossil types to be able to positively identify as even being a fossil. There are heaps of random shapes in rocks across the world, and sometimes one will look like a particular animal print, or as if a toy boat had been left in the sediment, and all sorts of similar things. It is not uncommon for rocks to crack and flake in a shape that can look like a footprint, or even a shoeprint. This means one cannot make a case for a one-off shape being a single footprint. It is necessary to have a series of footprints in a trackway to make a case.
Dubious ‘giant’ physiology
The ‘footprint’ is roughly four times the size of an adult footprint. Applying that 4x to other linear dimensions would suggest a human some 7 metres (23 feet) tall. The Bible does mention that there were some giants in the pre-Flood world, but ‘giant’ is a relative term. To some people groups today, a US basketball ‘dream team’ would certainly qualify for that description. But there are limits to the degree to which one can speculate about the size of past members of the human race, and it is likely that the approximately 2.7-metre (9-foot) Goliath was at or very near the size limit. Scaling up the linear dimensions four times means that the human would have weighed around six tonnes (2D measurements like area would be increased 16 times, but mass as an approximation to the volume of a sphere (3D) would increase by some 64 times. Thus, though the mass would have increased 64 times, the cross sectional area of the leg bones would have only increased 16 times. So, in order to support the weight, the leg bone thickness would have to be increased dramatically. Many other aspects of this ‘scaling up’ issue would mean that the entire human body would have to have been totally ‘redesigned’, such that the person would look very, very strange indeed to our eyes, and not just because of the ‘giant’ aspect. Further, such a person could not have any genetic continuity with any humans on earth, for the same reason: i.e. so many aspects of their body would have to be totally different in order for them to be able to survive at that size in our gravity. Therefore, if this were a giant footprint, the creature that made it certainly would not qualify as ever having been part of the gene pool of the human race.
Summary and conclusions
This giant footprint suffers from giant problems—and numerous problems at that. Even if this were a footprint, it wouldn’t be a human footprint because the redesign necessary for such a creature to exist at such a size would be so severe that the creature couldn’t have any genetic continuity with us. However, we can dismiss the claim that this is a footprint because there is only one print, not a trackway; it is in granite, an igneous rock that no living organism would have a hope of leaving any sort of impression in; granite can produce some remarkable weathering features; and the granite outcrop bears numerous tell-tale features of patterns of weathering likely to produce a similar class of shapes at random.
We have a tendency to see patterns and purpose in things where they don’t exist. The textbook example is seeing recognizable shapes in clouds—we may sometimes see a face, or a balloon, or a rabbit, or any number of shapes we are familiar with. The same can be said of many rock formations, especially when one considers the names of many rock formations: e.g. “Glasshouse Mountains, “Giant’s Causeway”, “Bear Rock”, “Murphy’s Haystacks”, etc. The list is almost endless. Trace fossils, such as footprints, are often tough to identify in sedimentary rocks because weathering patterns can produce an amazing array of shapes that it can be hard to know whether an impression is a footprint or a weathering feature. However, when the print is in an out-of-place context, such as in igneous rock, the conclusion is rather straightforward—it is not a footprint.4 And it is certainly not relevant to either the pre-Flood Nephilim or the post-Flood mention of ‘giants’.

Yes, you are welcome to criticize Michael Tellinger if you wish. As far as I understand he was also just trying to make sense of it. As to your arguments, they don't say anything except that you have also made up your mind and will argue anything around your conclusion to make it valid. You may be right but you may be wrong, you cant use your argument to get to any conclusion. But actually, christians shoudl not even try to get involved in science as you based most of your life on airy fairy premises in any case and we know you would normally go out of your way to make your airy fairy world more real than the actual one out there. To me this looks like a footprint and the probability for that is higher than evolution or the existence of God together.
Everyone is “just trying to make sense of it”, but that doesn’t mean that Tellinger has done a good job. There are only two basic possibilities—either the formation is a footprint, or it’s not. Unlike evolutionists, biblical creationists actually have reason to think giant footprints (though likely not quite that size) might be possible—and yet we still dismiss the idea that this is a footprint. We’ve offered arguments for our conclusion, which you’ve simply dismissed with a ‘you might be wrong’ and a ‘you just assume it’s not true’. If this footprint is genuine, show how it could be produced in granite. Show how our weathering explanation is implausible. Show why this one ‘footprint’ should be considered real when a similar situation in sedimentary rock would produce considerable skepticism.
With regard to Christians and science, if Christians didn’t get involved in science, there wouldn’t be any science to speak of! Only Christianity gave birth to a fully-fledged scientific enterprise (see Creation scientists, The biblical roots of modern science, and Why does science work at all?).
I think you're explanation for the cause of the "footprint" was excellent. Before reading the article I would have had no idea what could have caused it. I do however have a problem with the response Shaun Doyle gave to the comment from CK., South Africa. It seemes as though Shaun responded out of anger, and a bit of arrogance. The response showed no love towards the reader. And if we are going to lead people to Christ we must love them to him. We can't argue them to him. Overall, I love your website. I thinks it's a great educational tool. Thanks for taking the time to read my comment.
I don't feel that Shaun was being arrogant. I think he was just stating the facts as he sees them.
