This is incorrect. The pyramids in South America are over 20000 years old. They're so old their bases are covered in forests. The vast majority of technology has been here before.
Nope. 20 THOUSAND with a T, years old. The history you were taught was a self-serving history formulated by Europeans so they could steal the 'new world'. It was only new to them.
I understand human migration, and no history is not lies taught by Europeans. Obviously there was people here long before European settlers, it not large civilizations that old.
I am well aware that there was migration to the Americas before the land bridge migration. This link doesnt claim there were massive cities 20000 years ago though.
It shows you that there were people here tens of thousands of years ago and that they were negros. Which is completely contradictory to mainstream history. There's more links google em
Interesting change of topic. Yes I know there is evidence of African, and Australian aboriginal migration to South America. You confuse grade school history with mainstream history.
Doesn't matter what you call it really. The official story line of transatlantic slave trade etc. is a lie. It was created to support European colonialism Not sure how thats mainstream
