Billy Meiers is one of the more clearly provable hoaxes around.. don't get me wrong, I believe some of the stuff I see -- but if you're going to pick someone to believe, don't let it be Billy Meiers :)
All of his photographs are proven around 4th generation edits (meaning the editing process went through about 4 generations before he came out with the final draft).
*shrug* then again, maybe the proof that it's a hoax is a hoax. Lol. I don't have first-hand experience with the evidence.
The guy is mentally disturbed to say the least. "Billy" the kid... hahaha. Anyway, I heard about this guy a long time ago and I remember that mini saucers were found in his barn.
One of his videos showed a massive UFO over some hills. The flaw, however, was the road with passing cars that was in frame. If the UFO really was there I would suspect that people would be pulling over to view it.
The video itself is funny. The host explains meeting Billy... man the freak was hiding in the trees just starring at the host until he decided that he liked the host. Billy also claims that he is actually from another planet... well, that his spirit was put into that body. Whatever.
