Civilization Lost is a great documentary from the History Channel (available on YouTube) that lays out the evidence for a remotely ancient civilization that predates the currently accepted historical timeline and paradigm. They spend a good deal of time on the discovery of Gobekli Tepe, a relatively recent discovery of an ancient megalithic site which was deliberately buried and contains artifacts which have been dated by mainstream archaeologists to at least 10,000 B.C. The megaliths (giant stones) are carved, so this implies tool use. The construction of the site also implies a society and organization beyond the supposed hunter-gatherer society assumed to be the norm at the time.
Interestingly, the date coincides with the date the controversial author Graham Hancock has been pointing to since the publication of Fingerprints of the Gods many years ago. While considered a kook by mainstream archaeologists, I find Hancock’s arguments to be fascinating. Could he be wrong? Sure. But I like thinking about this stuff. His answer to initial skepticism of his claims of a lost ancient civilization were answered by his evidence: a global catastrophe flooded the coastal areas of the continents, where ancient humans (as modern humans) lived. As underwater archaeology progresses, we’ll see more and more evidence of this. The discovery of sunken city of off the coast of Cambay, India and the exploration of so-called Doggerland between England and the continent of Europe are starting to bear this out.
Usually these types of documentaries tend to go off into fringe speculation, but Civilization Lost stays clear of this kind of stuff. You won’t hear mention of Atlantis or aliens.
I’m not sure why mainstream science is so resistant to looking into these kinds of ideas. Science seems to be so sure of their infallibility, until of course a new theory bears out to be true and they have no choice to accept. Perhaps all of this is indeed wrong. Fine. But there are unexplained facts about the origins of human civilization that science to date has yet to satisfactorily explain. The leap from hunter-gatherer to Sumer was just too immense. But I’m not here to argue that point.
