Great Podcast with Joe Rogan and a couple of archaelogists who suggest that around 13,000 years ago, we were much more advanced (at least a great portion of us) than previously thought. Evidence shows that the great sphinx was built much much longer ago than thought, as was perhaps the great pyramid. These scholars believe that, therefore, (and for a few other reasons) it was not the Egyptians that built these structures). One other reason given is that there is no reason to believe that the Egyptians could cut stone like that so precisely (including granite! There has never been any sort of saw or cutting tool found in Egypt bigger than a small one hand copper hand-saw. And while there have been many depictions and Ancient Egyptian art showing handsaws, there has never been any drawings of large saws found. Not to mention, large saws couldnt really cut the granite stones anyways. But the most intriguing find is Gobekli Tepi, which predates Stonehendge by 6,000 years and is much much larger and sophisticated and impressive from an engineering standpoint. Then the skeptic Michael Shermer got wind of this podcast and came on to confront these two scholars, and really got a drubbing. Really did, from both scholars and Joe Rogan himself. Here is the second podcast with the debate including Shermer.
