I would argue that humans have in fact proved far superior in the way of survival. Particularly in terms of intelligence and motor function. Hence why we exist literally everywhere while many species of monies and apes are going extinct
I wouldn't know about the fossil evidence, I haven't done nearly enough research on the subject and I'm looking to do so. I haven't looked into any archives for data surrounding fossils from those time periods, so you very well be correct in that, though it seems like there's more to that statement than meets the eye.
Anyways, I would like to ask similarly, since you would know more than I about religion, what exact evidence points to God?
