DNA testing of Tierra del Fuego human remains demonstrate that they are related to Australian aborigines. More and more of these remains are being discovered scattered throughout South America.
But that isn’t all.
There was a compelling cosmic catastrophe 13,000 years ago, an event hugely important historically for North America.
The book detailing this cosmic event is “The Cycle of Cosmic Catastrophes” by Richard Firestone, Allen West, and Simon Warwick-Smith. (Firestone is a nuclear physicist; West was the owner of an international scientific consulting business; Warwick-Smith is a geologist).
Don’t allow the tacky illustration on the cover to deter you from reading this book (why a Hellenistic sculpture is depicted is puzzling.) This book is scientific in its thorough address of heavenly and earthly events.
According to these authors humans lived in North and South America for years before this event caused mass extinctions and a collapse of the ice sheet in North America.
