I'm very much looking forward to reading Graham Hancock's forthcoming book, Magicians of the Gods, which is a sequel to his 1990's classic, Fingerprints of the Gods. Here is a brief panel discussion, moderated by James Tyberon, with Dr. Robert Schoch of Boston University. Dr. Schoch has been the target of ridicule from the acedemic establishment for 25 years because of his paradigm-shifting research into the weather-induced erosion of the Sphinx of Giza. Well worth a 10 minute or so watch. There are plenty of longer interviews with both men available if you want to delve into their work in more depth.
