I had a bit of a discussion on reddit recently, where we debated this for quite some time.
What are your thoughts about extraterrestrials being here on earth already? Why would people such as Gordon Cooper (Mercury & Gemini Astronaut), Edgar Mitchell(6th man on moon), Paul Hellyer(former Canadian defence minister), Baron Hill Norton(Former British Chief of Defense Staff) and Buzz Aldrin(2nd man on moon) speak out about things like this if it wasn't true/real? Wouldn't they just risk being ridiculed?
Better list of people can be found >>here<< (with videos / articles etc), Also official FBI files from fbi.gov relating to ufos / extraterrestrials.
Don't kill me now , I think it's a valid topic to dicuss.
