Interesting theory, but there’s a whole lot of speculation padding it as well. I’ll reserve judgment until they find some ancient sake bottles or something.
” a whole lot of speculation padding it as well”
No kidding. Just using similarity of arrow heads seems like a huge stretch. There are only a few ways to chip a stone arrow head and it was probably conceived all over the world. And, how slow was the journey from NE Asia to North America? 10 years? 100 years? 1,000 years? A lot would be forgotten in the longer time periods, new ideas conceived. I would think it would be very hard to connect something as simple as arrow heads over 100 or 1,000 years.
I’m not even an amateur. I know nothing about such anthropology. But this seems like a big stretch.
True. But there is a lot of speculation in what is currently considered history.
