UFO's ..Do You Believe?

So for a while now there has been this whole speculation of UFOs and aliens existing. Some people say they have seen one or the other and some people think its all a bunch of bologna. Well I for one believe in life beyond this planet, I mean why would earth be the only planet that holds living beings in this entire universe? (refer to this video I came across http://www.youtube.com/watch?v=ZotqTnpAEqs )And how do we explain the Egyptians, Mayans and Incas architecture? How could they have built those gigantic structures with out some sort of help? I mean look how precise the pyramids were? How could they have built all that with only humans doing all the work?

People all over the world have reported seeing "flying saucers" but you mean to tell me ALL of these people are delusional, drunk or just plain crazy?

The list goes on and on...and yet the higher ups still try to hide this and deny things...now I am sure that some of the videos, pictures and stories may just very well be lies but some of this stuff has to be true! I don't believe we are alone, there is no way that we are the only ones in this entire universe.

"It's incredible to think that we might be the only intelligent, living system in the universe. That's not credible anymore," Apollo 14 veteran Edgar Mitchell told WPBF-TV in West Palm Beach, Fla., on Friday.
