Does UFO exist?

I'm not sure they're existing now. I have read many articles about that. I also have seen many videos about that. But still there is no clear clue. Say they exist, so what? So far I only see they really exist on movie. Let them live in our imagination then. UFOs remain mystery forever.

I don't know but i think it's true because the universe is extremely big and maybe someday we'll see them.

They might exist, but as of now there is no real proof of their existence. I think that if extraterrestrial life were out there, we may have known of it before now.

If you mean ufo as in any object that is in the sky that you don't know what it is then yes it does exist. I don't think the ufos are extraterrestrial though. I think the ufos may be birds, aircrafts, or any thing that appears in the natural world.

in reality i like to believe that may eb is possible the xistence of UFO..i think it would be better if it can be true..but unluckly till now we never had real proofs about them..so. we will see in future..

I have to say...what difference does it make if they do or not? If they are living in space, and can come to Earth....(2 things we can't do in "their world") obviously they are much smarter and more intelligent than we are so we'd better watch how we deal with them! They are that smart and intelligent...they can annilate us instantly if they wanted to, so we'd better just leave them alone!

over the years I'd swear I've seen UFOs in the sky but........I really don't believe there's such thing...hmmmmm but then again I wonder lol
