People (including me) believe that the government is denying all crashes, autopsies, etc, and hiding all evidence of extraterrestrials. But there is more than enough proof out there. Many believe it is all a hoax, the aliens, the videos, witnesses, etc. This is a thriving question, "are we alone?" There are tv shows about it, factual or non-factual, such as UFO Hunters (factual) or the X-Files (non-factual), and countless movies. Movies and shows have gotten us to believe of the gray, large insect eyed, three-fingered alien that look similar to us in body build, maybe it is just in our head, or maybe it is real. There are countless videos on youtube trying to prove existence.
I remember gathering all these videos off of youtube, all removed, the reason; "This video has been removed due to terms of use violation." Not a very good reason, but here is one still online:

So are you a believer? What is your proof? or are you a non-believer? What is your proof?
