Don’t understand it well enough to truly know if the cultures are related or not. But i do know one thing,, a culture that understood astronomy and could build such buildings, and do such amazing stone masonry,,could have certainly have built boats and ships.
Remember, it wasnt so long ago that America was populated onlt by landbridge over Bering straits, and a southward spread 12,000 years ago. Now it’s all but a certainty that clovis culture came from europe much earlier following the last ice sheet. Also,,,sites in South America predate the old 12,000 year rule.
This is a tough field in which to truly establish hard facts. And it’s changing rapidly.
And I saw none in the pics.
