One problem I think with UFO's is that they are usually seen at night time in the dark, right? The thing is, it's dark. You can't see anything. Just everything in the sky is a UFO because its unidentified as you cannot see it. I'm sure people see many things in the dark that look just like the things in the movies.

I do not think there a beings from other planets flying in our skys, or ever have been for that matter. But when you think about it, the universe is so big, what counts as an alien or other living organism from outer space? No one knows just what kinds of things are out there or what they look like, they could be so small we cant even see them.

So I say "I don't care about that".

I don't think they exist. Our senses are easily misled and we can make warped judgments under stress, fear or exhaustion. A lot of sightings could actually be attributed to light from airplanes or military aircrafts. Obviously when these sightings are reported, nobody's going to step up and admit that they were undergoing secret military training or spying activities.
