Thanks for the link. He does seem to be hinting at Ancient Aliens with that two-day orbit concept... except that his reasoning doesn't really check out unless he disputes the dates for a lot of the sites on that orbit. For instance, Mohenjo-Daro was abandoned around 1700 BC, Persepolis was built in the 500's BC and destroyed in the 300's, and Preah Vihear was built in the 800's AD. That also seems to rebut his argument that those sites' stonework techniques were a remnant of some very ancient civilization; if so, how come Cambodia remembered them until the 800's AD without those memories being recorded anywhere? That said, I really do agree with him that more exploration on the continental shelf would be profitable. And, the Younger Dryas impact is an intriguing idea.
