Not if you actually mean, "do you believe in alien spacecraft". Has there never been the slightest shred of evidence to support this?
But people can and do see things in the sky they themselves can't ID. In this sense, it is not a matter of "believing". We *know* people see things in the sky they can't ID. But the least likely explanation for these sky-blobs is for them to be alien spacecraft.
A lot of dorks
No.
Only if you believe they do.
I guess the strongest evidence for not believing in UFOs would be that they haven't landed and introduced themselves. For some people to believe they would have to see the beings.
No Most people don't even believe in Ufos so no need to be worried
There are those among us who believe that UFOs have always been hovering nearby.
Astrobiologists. //I believe UFOlogist is the correct word, a person that studies and pursues all things alien.
People have reported sightings of UFOs in France, but there is no proof of their existence.
The ones who study UFOs are called Ufologist. They study every thing about unidentified flying objects (UFOs).
astrobiology
There is no credible evidence for this.
