Mark Olly is the author of several books. He's an archeologist, researcher, host, media producer, educator and musician. His most recent book is about the Crystal Skulls and Human skulls. He explains what the crystal skulls are, where they are from and the approximate ages. We also go over the three camps regarding the origin of man (homo sapien sapien). That's just where the fun starts. We end at the end. But is the end the end? What??? You have to listen to find out.
