Richard Hoagland is the guy who thinks ancient Martians built a giant monkey-faced monument staring up into the Martian sky. He obviously should be taken seriously.
Didn’t I see that on Planet of the Apes?
LOL! He sounds like a distinguished expert. You’re right, I shouldn’t act like an elistist liberal..I should take him seriously (snort)
He also promoted the "greenhouse effect" aka "global warming" in articles he wrote in the 1970s. IIRC he also believed that the Hawaiian volcanic "hot spot" was probably caused by an interstellar space ship's fusion drive when it crashed into Earth in the distant past. Scientifically he's right up there with Von Daniken.
