IAC's whole theory relies on God moving the continents apart at an incredible speed. His whole theory relies on unnatural and supernatural occurances, not natural ones.
If IAC's "rapid lithication" deluge theory were correct, then we should see literally billions of human, duck, kangaro, etc. fossils all bundled together in the same layer of sediment. The sedimentary rock layers we see should be literally overflowing with fossils. Yet in the real world we know that fossils are actually a rare find, and fossilization a rare occurence.
No humans with giant sauropods in the same layer? No humans with any creatures which existed millions of years ago? Interesting...
IAC's explanation is that humans were more mobile than every other animal which is why human fossils are only found at the highest level of sediment. That's funny, because I always thought there was a plethera of animals more mobile than us (lions, cheetahs, leopards, swamp cats, pterodons, birds, etc.).
In any case, if the "more mobile" theory is true then why is there huge flying reptile (pterodons) located thousands of feet deep in the sedment? I always thought flying was more "mobile" then walking (humans).
