As I understand it, has the American government a deal with an Alien race !!
They are aware of the excistance of several different spiecies, large gray's, small gray's, the 'Nordics' (they look like us), and the reptilian.
The stories of all the different people are so simular, and so specific concerning the details, that you can't ignore them.
The lectures of Phil Schneider are very clear. He was a geologist for a company that build Deep Underground Militairy Basis for the government. They accidently opend a place occupied by what he called 'large gray's'.
