Yeah yeah. I know it cant be. But I recently saw a documentary on History Channel showing flabbergasting pieces of evidence and witness accounts which I'm finding really hard to reject. I also once saw the documentary of Bob Lazar who claimed to have examined a UFO. I don't know what he examined or what exactly happened but that guy wasn't lying. He gave quite good accounts of his experiences. The most rational explanation can be that most of the evidence is fake and the other stuff is some kinda technology that the common man is not familiar with. What is your stance? Here's a bit you might wanna look at: http://www.ufodigest.com/news/0308/invade-cnn.html
As long as the UFOs are proved conclusively beyond doubt, they will be considered as imaginary characters
unidentified? yes. extraterrestrial? maybe (meteor, asteroid, whatever). intelligent source? no. Since we (humans) started to use our brain more than an average chimp, we always faced questions that we weren't able to answer at a certain point. Some people chose to invent "god", others inventend some mysterious energies or other stuff. Some simple say: "We don't know yet. Time will come, when we know. I'll wait until then"
