22,000 years ago is a LOT earlier than what science agrees to (at this point), but fits given other evidence found but thought to be in error, like Arlington Springs woman, Luzia from Brazil, or the ancient skull found in the Mexico City museum.
I’m still thinking the Solutrean culture from France, the Aboriginals from South East Asia, and a boat/sea farer culture from Japan all beat the Beringians to the Americas.

I was reading a totally unrelated story about the paddleboats (riverboats) that were used at the turn of the century for travel between England/France and New York. Riverboats don’t do well in high waves but nonetheless they made many, many successful trips between the continents.
From that story it was easy to imagine how early man likely traveled the same route using small boats. or perhaps the artic sea ice extended far enough south that there was a land/ice-bridge that hunters followed until they found America. Or even by a southern route, from Africa/Middle East to South America and then north, lending credit to the stories from the Maya and Peruvians who claimed there were races of whites/caucasians living in mountains prior to their own arrival and whom they slaughtered.
