Are U.F.O.s real?

• Definitely yes, I've seen a U.F.O. up close.

• Yes, I've seen unexplained aerial phenomena.

• Probably, someone I know and trust has had a U.F.O. experience.

• Possibly, there are so many stars with planets in this vast Universe.

• Possibly, but who says they must be extraterrestrial, maybe they are interdimensional or demons, or...

• Probably not, there is no credible evidence.

• Definitely not, it is impossible or goes against my belief system.
