Have you met most geologists, archeologists and historians?

They're like the nerdiest, most humble people I've ever seen, some of them are even vaguely disturbing because they're
so into their chosen subject it gets a bit sad. I can't see these people wanting to cover anything up. If they found anything that groundbreaking they would probably actually piss themselves
But seriously, early humans , and I'm talking pre-civilization, hunter-gatherer nomadic humans that migrated across the planet some 50,000 - 30,000 years ago, were just as intelligent as we are today. They were literally exactly the same as we are now, except they didn't have the benefit of a mutual collective knowledge of things, because they lived in small dispersed groups as compared to today. And they probably had a different average height, heh. But the fact remains, they
were capable of everything that we're capable of now, and to say that they needed the help of aliens from Orion is a great discredit to them, if you ask me. Great example is bone needles found in Siberia that date as far back as 20,000 years ago. Needles for sewing animal skins together for clothes and shelter - a genius invention even before we'd discovered how to farm! Being able to do that meant we were able to survive the ice-age, and have nomadic houses that could be erected and taken down in time to follow the herds.
There actually isn't
any concensus on how and when early human civilizations started. The Evolution vs Revolution debate still rages amongst biologists, historians and archaeologists....
There are stacks of exhaustive evidence pointing to our African origins, though, and a lot of it is buried within our DNA. We carry our biological history with us
Stephen oppenheimer fuses genetic science, archaeology, climatology and fossil study to come to his conclusions - that's a lot of corroborative evidence that's very hard to dispute.

I'm not discrediting the guy in the OP entirely, I just think these finds mean something else to the conclusion he came to, and that's just my opinion. There's plenty of unexplained archaeological findings out there that make no sense whatsoever, and they shouldn't be ridiculed or cast aside - when they first found and brought back a duck-billed platapus people thought it was a complete hoax...
