For just one example of many throughout the Americas:
"The Narragansett Indians are the descendants of the aboriginal people of the State of Rhode Island. Archaeological evidence and the oral history of the Narragansett People establish their existence in this region more than 30,000 years ago. This history transcends all written documentaries and is present upon the faces of rock formations and through oral history"
http://www.narragansett-tribe.org/history.htmIt also "transends" the folk who may have treked over the Bering St.
There are other scientific date for native habitation much older in the Americas.
It' quite possible some came over the Bering Straits but that doesn't mean there were no people here already.
The "professionals" have been stuck on stupid for so long, it's not likely they'll ever abandon the original theory.
It would seem that, since, for centuries the folk in the "Old World" didn't know that the "NEW" world existed, then it followed, in their reckoning, that the people they found here had to've gotten here, somehow, from the "Old" world. And once the experts have 'discovered' something, they cannot let go of it - no matter the evidence otherwise.
Funny thing is - the Indians knew that the "Old World" existed "across the sunrise sea" long before the first white men showed up.
The traces of cocaine and nicotine found in Egyptian tombs shows clearly to me that the current accepted assumptions are false. Major population centers are to this day still located near major waterways and/or the ocean. Humans have always been sea faring. The traces of much of the past are underwater.
