Yes. His last series was great, can't remember the title. I think it's undeniable that there's a cycle (probably ca 12k years) and that we know almost nothing about the civilizations before the last cataclysm. The mystery schools all share the conviction that Atlantis and Lemuria were the civilizations preceeding our time. I think that is probably true. Either way, there were civilizations in pre-historic times that had technology we can only dream about. If you believe the History Channel it came all from "ancient astronauts". Personally I find that leap to a conclusion just as unnecessary as I find it suspicious. Seems like a red herring.
