The 'First Nations' have some explaining to do

[Rokcet Scientist]

If europeans colonized the americas in any substantial way before the Native Americans (an amusing term, regardless, and discussions like this emphasize exactly why)

I may have news for you: the Solutreans weren't the first hominids to get to the Americas either. I bet Homo Erectus already got there maybe even half a million to a million years earlier! Walking, wading, hunting, and gathering along the world's coastlines. When sea levels were 400 feet lower than today.
Any remains would now obviously be submerged, and far out to sea.
