I'd just like to start by saying this is my opinion right or wrong. I believe that the Gov't, at least Cells of it, know all about Aliens. They've seen them, they have their crafts, they know. The can Easily monitor All transmissions in and out of earth. I believe that the current "Project Disclosure" team is being totally honest and that SETI and NASA are either in the Fooled employee or "In the Know" Groups, with almost ALL of them just having been fooled.
Anyways, I know I'm a crackpot... heh yeah right. I would suggest anyone wanting to know what's Really up going to

Of course this is just an opinion, an Informed one, but just an opinion.
