heres this?

Explanation:

The first arrivals keep getting older and older because we’re finding more evidence as time goes on. Right now we can solidly say that people were across the Americas by 15,000 years ago. But that means people were probably already well in place by then; and there’s enough evidence to suggest humans were widespread 20,000 years ago. There’s some evidence of people as far back as 30,000 to 40,000 years ago, but the evidence gets thinner and thinner the further back you go. It appears there’s not a single arrival date. No doubt there was a first person walking in, but when that happened is well before 20,000 years ago.
