One major thing both sides have in thier favour is "go up there, have a look around and prove me wrong". They both know we can't visit space, witness the truth ourselves and prove them right or wrong.
If there is all sorts of secret stuff going on in space (there's plenty of it going on down here) how are you and I going to go up there and catch NASA at it.
On the other hand, John Lear also knows we can't just pop up there and see for ourselves. So he can say what he likes, no matter how outlandish, and there's nothing we can do to investigate his theory 'on site'. He can make it sound all scientific, get others to support him, and use his notoriety to back himself up. But in the end, he knows we can't visit space and prove him wrong.
I might have to dig the miniature chip out of my body though.
Damn thing keeps affecting the TV reception
