Has it never occurred to these scientists that they might actually have this entire thing backwards? That it is just as possible that homo erectus, or whatever designated homo floats their boat, moved from here to wherever long before their so-called dating system begins? This continent has been vastly underexplored for historical data. And that this continent contains a wealth of knowledge that paleontologist only dream of and speculate over.
Why do they seem to think that this entire expanse of land was virtually empty before our “betters” from other continents decided to give it a try? It’s a ridiculous assumption.
Could it possibly be because there are NO monkeys native to North America? So it doesn’t only screw with their timeline, it whacks their theory of evolution dead in the head.
So, your saying that the garden of Eden was in America? Who know.
