I've seen one of those episodes, with cooks who think that the Pyramids were actually built 12,000 years ago, or at least the foundations. Why? Because if you map out the topology of the various building sites and you compute the position of certain celestial bodies as they would have appeared at that time from that vantage point, they coincide. Behold, the proof! This is the same kind of people who read the Bible and try to find "secret messages" in it.
It's a travesty that a channel that calls itself the History Channel is peddling this stuff.
Interesting? Sure, why not. Amusing too. But presenting it as science is another story of bad science.
