What is wrong with 100K years ago for the "First American"?

According to the internet (I have been curious about bighorn sheep):

The ancestors of bighorn sheep resided in the mountain and desert regions of Eurasia from early Pleistocene. Crossing the Bering land bridge during the late Pleistocene (100,000 years ago), they spread to mountains of Europe, North Africa, Asia and North America. True goats (Capra) are closest relatives. May 16, 2023

Since there were reasonably competent hominids all over Asia by that time, I cannot imagine why they could not have walked in the same places as those "First Sheep".

American archaeology is such garbage. There are unsolved problems all around and data going unexplored. But it seems most of the money goes to studying pretty pottery.
