Oh, he's an actual legitimate person alright. No doubt about it. He's a human being. But I find it hard to believe that anyone could spout the continuous stream of howlers that he does and not have some mental illness which permits him to believe it. Did you know, for example, that NASA chooses launch dates and such based on numerological or Freemasonic symbolism? Me either.

"In regards to the arrival of extra-terrestrials and the destruction of Phoenix, Arizona, the SETI (Search for Extra-Terrestrial Intelligence) Institute detected a signal in the direction of the star called EQ Pegasi in the Pegasus Constellation in September of 1998. The SETI institute dismissed the signal and no attention was paid to it until an amateur radio astronomer named Paul Dore in England picked up the same signal. A series of strange events ranging from a called off press conference, a SETI denial and then support of the theory of the signal, intimidation of Mr. Dore by the NSA and disinformation put out in the press has been decoded with Freemasonic symbolism by Richard C. Hoagland of the Enterprise Mission. This became known as the EQ Pegasus Saga."

http://www.enterprisemission.com/moon3.htm A few quotes...
A “moon” -- but a moon like no other known, one which has intrigued and mystified Earthbound astronomers for centuries … which now, it turns out, is quite possibly a very ancient spaceship … placed in orbit around Saturn for “some reason” … a long, long time ago.
When it was new, it may have even looked a bit like this (below) -- complete with “equatorial ring.”
(Which means, of course, we now have to add George Lucas to our growing list – and ask where he got such an extraordinary concept ….) 
Dun duh duh duhhhhh dun duh duh dun duh duh!!!! [/Star Wars Theme]
Another quote...
But, because of the deafening silence coming out of NASA on what it already knows but won’t release (let alone suspects!), about the glaring anomalies we’ve now identified about this “moon” … we are left with only one sad but inevitable conclusion:
NASA, again, has decided to “tough it out” … to officially say nothing -- like it has treated all its other discoveries of “extraterrestrial ruins” in the solar system … over the last 30 or so years ….
You can just hear the X-Files music playing!
