Possibly.

Sure, unidentified flying objects? Of course, but that doesn't mean they are aliens from other planets.

Heck yeah. Oh yea like some freakin idiot on mars just put lights on a balloon and let it go and just keeps on doin tht. And then he just passes it on from generation to generation until some smart guy say "SCREW THIS, THIS IS JUST FREAKIN GAY"!!!!!!!!!!!

UFOs exist people!!! you would believe in aliens if you saw the movie fire in the sky!!! its based off of true stuff.

they probably exist but nobody really knows. only the people in area 51 have the ideas, hard question

yes they are always watching you through your window at night have you never noticed they LOOK PEOPLE THINK there there check i have seen them have you??????????????????

Yes, but not from aliens. They're made by governments. There's evidence that the government has been creating UFO's secretly. There's also evidence that Nazis made some.

Clarification on Area 51: It's not some kind of alien place. It's a secret government area that employs thousands of people. The government created the lie that it's full of aliens to cover it up.

UFO is defined as unidentified flying objects! That means anything you see flying through the sky is a UFO! It doesn't mean theres aliens or anything. It just means you don't know what it is.

Of Course, UFO stands for Unidentified Flying Object - a spy plane from another country would usually be unidentified to the other country.

If I threw a pen at someone and they didnt know what it was it is a UFO to them.(NOT containing aliens)

You all have a point.

A UFO is an unidentifiable flying object. So if I saw a bird, but it was too high to figure out what it is, than it is a UFO to me...
