Do you believe in UFOs?

Personally I have never seen a UFO or anything really that I could not explain, but it's quite obvious that a large amount people around the world do.

With the huge amount of sightings reported around the world, there must be something strange flying in our skies. Whether these things are from another world, or our own secret projects, only timer will tell. Personally I believe somewhat that we're not alone in the universe, I just hoping we get some kind of disclosure soon to settle it all.
