I think the theory of the dry bering land strait has lots of evidence and was how the last wave of peoples came here. The is plenty of evidence suggesting though that people were here upwards of 100000 yrs ago. There have been tool mammoth bones found in cali that are the oldest. A lot of the mounds in places like Ohio apparently date to about 40. Also, lots of aztec and mayan cultures have clues suggesting they were around much before the end of the younger dryas/last ice age. Interesting stuff
I’ve been listening to a guy named Randall Carlson who is a geologist. He has been gathering data his whole life and has come to sort of a conclusion that there was a major flood event 12,800 yrs ago. This kind of dovetails with another researcher named graham hancock who thinks there were civilizations before the contemporary idea of 5000 yrs ago or so. Also dovetails with many cultures flood stories. Cool ideas if any of you are interested
Actually there is very little reliable evidence to suggest anything older than 20-30,000 year for human habitation of the Americas. The mastodon site in California has very few believers among reputable archaeologists. The other problem with the older than 100,000 idea is that it pretty much pre-dates the time line for Homo sapiens. It would have had to have been Homo erectus. No corroborating evidence backs up the findings; neither fossil nor DNA.
The older than 20,000-30,000 year human habitation relies on the notion that the Americas were peopled by humans arriving by boat along the west coast so that they were able to get around the glaciers blocking overland arrivals.
