Answer 2

I'll leave the sentence construction up to you.  A corridor is thought to have opened up between parts of the former ice sheet covering Alaska and Canada, and that allowed mammoth hunters to penetrate into the continent around 11,000 years ago; the first humans to arrive.  They came in from Siberia and, within a matter of a few centuries, their descendants had already reached Patagonia at the tip of South America.  The mathematics of the plausibility of that only require an advance of around eight miles per year to be involved which, for hunter-gatherers, ain't very far at all.  The entry from Siberia was possible because the then lower sea level left a landbridge.  After all, lots of other big mammals traipsed between Asia and North America, including the mammoths.  Horses, bison, elk, reindeer, beavers, brown bears and more all then lived on both continents

There are possibilities that human incursions happened by other means as well, but the available evidence is broadly in line with the scenario sketched in above being the main source of North Americas human pioneers.  Their descendants, the Indians (NDNs, native Americans, insert your own favoured term), spread over two (probably) entirely unoccupied continents.

You won't need what follows, but it could be of interest.

Their are various reasons why some living Indians are uncomfortable with this mainline interpretation, and some wish to see it as part of the continuing campaign of white racism towards them.  Some early advocates of this landbridge idea were at least in part racially motivated.  One of the implications must be that those early pioneers managed to eradicate most large mammals on both continents including all elephants, horses, camels, various sabre-toothed cats, most lions and and and; an extinction tally of something like 75% within less than a thousand years.  That detail doesn't fit well with prevailing Indian philosophies.

However, as large mammals definitely did travel between Asia and North America, that in itself is extremely strong evidence for a landbridge.  If mammoths could cross, then so could people.
