You point to the polynesians but it has been established trade routes existed to the northern part of north america long before the vikings. This is evidenced by the mound builders. The Serpent Mound in Ohio gets all the accolades but there are mounds further west in the northern states. Also the Serpent Mound is not unique as there is another in Scotland. Like I said I watch these shows for there historical value not their entertainment purpose although I am entertained from it. That is North American history you won’t find taught in any high school. Some would say the druids from Ireland/England came over in regards to the stone structures found in the North East. This isn’t even including the Land Bridge Theory. Then there is how those stone structures that just happen to align with the solstices rather than be for the use of storage of food. Then you have the monolith that could have been used for human sacrifice, but not sure if that was its actual use. It is shaped like a mortuaries table. So it could have been used for the purpose of blood capture in some fashion. Too much real evidence rather than “circumstantial” evidence pointing to the movement of man due to trade and exploration throughout the ancient world to be glossed over because someone is a naysayer to actual history. Heck, most thought (and some still do) the world was flat and the Earth was the center of the universe. Bah! Get real!
I know the mound builder stuff very very well since I was raised in that area. There was an Adena\Hopewell (Can’t remember which Adena or Hopewell now - 50 years ago!) village excavated near my grandfather’s farm. I saw the excavation as a kid. I know the claims I don’t see the physical evidence. You pile up dirt it makes a mound. Snakes have impressed people all over the world & through all time & cultures. That in itself doesn’t make them connected other then the fact humans did it & humans share traits no matter when or where they’re from. There’s Neolithic structures all over Europe, a new exciting area of European archeology. They share some features with Neolithic structures elsewhere in the world. Why? Because in all cases humans built them.
Find me some Polynesian DNA in Ohio or WV! If its been found send me some links to some pubs.
To claim everything is connected without significant physical evidence insults the abilities of the ancient locals.
