Here’s what I suggest: do an outline of your own foot (without shoes or socks) and shrink the image down on a copier. Overlay a cut-out on the picture at the top of this article and than think about what you see.
Feet spread out during aging, bare or not. I have small feet theat are wide. But these weird toes aren’t from spreading; whoever did the forgery stuck them on at an impossible angle!
I have a toe that looks like E.T.’s head. If you saw my footprint in the mud, you’d swear I was an undiscovered primate species.
I bet toes spread out when you are running through the mud with a dinosaur on your ass.
They are not human foot prints.
Don’t worry, there are hordes of scientists out there who are willing prove it’s a hoax, if such is the case, using some sort of scientific dating method.
