OK kids, follow me on this one. There was an ice age and a Bering Land Bridge because a lot of the sea water was frozen as glaciers so there was a lot more shore line than there is now. Humans were migrating from Siberia across the land bridge. Do they continue inland where everything is frozen and there might not be much food or do they stick to the coastline where they know there is a lot of stuff to eat as they move south? I would have stuck to the shoreline. Eventually the Earth starts to warm and much of that ice melts back to water. The land bridge is flooded as are most of the coastal settlements. We’ll not find any evidence of these coastal settlements because they are all under water now. However, if the ancient humans migrated far enough south along the coast they eventually would have reached areas without glaciers and could have easily moved inland. Mexico was never glaciated. See how easy it is to be a scientist?
This is how Big Foot got here too.
If you’re talking down to Mexico, sure, I’d buy the Siberian thing. But I think most of the Siberians lived on or near the Bering Strait, with about a group of 70 or so, adventurer or outcast, persons making it to the American continent and begatting indians before the land was submerged
But if you’re talking South America, I’m down with the Aussies, “long ears”, tall white men with beards, who sailed west and settled the Pacific islands, then hopped across to Peru to the east, expanding the Y-DNA group (Asian/European) up the east coast of SA, possibly further, throughout the interior prior to the Amazonian culture, employing the same block-building techniques found in ancient Egypt. Eventually exterminated by war with the ‘short ears’, the blood-thirsty Marqueses of the pacific, and/or, north american indians with ‘viking-like’ canoes strapped two by two’ according to polynesian legends relayed to the Kon-Tiki expedition leader, Heyerdahl.
” a new line of evidence indicates that the first American clades split in East Asia, not in Beringia, which makes the gene flow of the Y ancestry from the ancestral East Asian groups even more likely “

after listening to a description of the boats from a polynesian storyteller, an european explorer might consider a ‘viking’ boat was being described and the best way to also describe the craft to his readers. Here’s a ‘viking’ boat on Lake Titicaca, Peru, the ‘birthplace’ of Inca culture:

The same could be said for the North Atlantic.
