I think perhaps you've answered your own question, since the bolded part above and the 20,000 - 11,500 BP I mentioned earlier are the same general timeframe where there was NO ice-free corridor. The possibility of an ice-free corridor before the Last Glacial Maximum shows no evidenced archaeological or genetic connection with human migrations into the Americas, particularly the US, thus far. All of which is still not helpful to any speculation of early NA migrating across North America only to manage their way back into Europe.

I have read here and there - and I think you and many here did too - that there are signs the Americas were being peopled long before 20,000 BP.
Now there may have been no ice-free coridor, but people also travelled by boat/canoe.
And that is what I said: anything that might prove a far earlier arrival into the Americas is very probably lying off the now submerged coast of north west America/ Alaska.
But yes, you are right, there is no scientific proof of that as far as I know of.
Liightlyy talked about the Red Paint Peopl/Maritime Archaic. Many finds in ancient Europe are very similar to finds in North America.
I think it's no coincidence, I think they were in contact.
There have been reports during the past centuries of people arriving in Ireland and Scotland. Some say they may have been Inuit who had drifted of course. I read here, on Unexplained Mysteries, about a discovery in Greenland (??), dating to only 5000 years ago of people who were genetically linked to Siberian people (if I find that post again I will add a link).
