Jason Colavito has called Giorgio Tsoukalos’ bluff — precisely what needs to be done to all ancient astronaut BSers. The research they produce is impressive only to non-specialists and those who never check their work. It’s pure paleobabble. Here’s the introductory paragraph of Jason’s post:

Ancient astronaut proponent Giorgio Tsoukalos claims that the fourteenth century Al-Khitat of Al-Maqrizi (1364-1442 CE) contains evidence that ancient astronauts assisted human beings in the construction of Egypt’s pyramids. This book, the most significant collection of medieval Arabian and Coptic pyramid lore ever assembled, has never been translated into English, so I have translated the passages dealing with pyramids to make this text accessible to interested readers. The following contains all of the significant references to the pyramids in the volume, though some minor allusions have been omitted. A fair review of the voluminous legends collected by Al-Maqrizi reveals no extraterrestrials, and no coherent story. In reading this material, I could come to no better conclusion that Al-Maqrizi himself: “There is no agreement on the time of their construction, the names of those who have raised them, or the cause of their erection. Many conflicting and unfounded legends have been told of them.”

So it’s put up or shut up time for Giorgio and other purveyors of ancient astronaut paleobabble. Jason deserves thanks from all of us who care that the intellectual heritage of the ancient world isn’t raped and pillaged to put forth modern myths.
