No.
Not in the sense you mean. UFO just means something in the sky you can't identify. Some people, for some reason, think the letters UFO stand for "Alien Spacecraft" but I'm not quite sure why! Any number of natural and man-made things may be seen in the air under conditions that do not allow easy identification. And if you don't know what they are, certainly you don't know they are alien spacecraft!
So the real question is is there any proof of alien spacecraft. No, there isn't. There is (contrary to popular belief) no solid proof of any life off Earth. The Universe is big, and life elsewhere seems likely, but odds aren't proof. After all, someone in the Universe has to be the first, and it may well be us.
UFOs are things in the sky that can't be identified. Obviously, in that sense, the answer is "yes" because people do see things they themselves can't identify.
Some people think that UFO, instead of being an acronym for Unidentified Flying Objects, means "Alien Spacecraft", somehow. But if you don't know what it is, how can you say it is an alien spacecraft? If you do know what it is, why say it is Unidentified? Doesn't work too well, does it?
So far, there is no proof of life elsewhere than Earth. It seems likely, but that isn't proof. And someone has to be first, and it may be us.
i believe there could

The Roswell NM crash in 1947 scattered depris for almost a mile. Had the military not stepped in and confiscated the wreckage there would probably be abundant evidence as proof of UFO's and/or alien visitors. Or if someone could find the alien body that was autopsied, that would prove it beyond a shadow of doubt. Until that time, the world may never know for certain.
There just isn't anything that could be called valid proof of alien contact. Just anecdotes, and no matter how high you stack anecdotes, they never transform into evidence.
There isn't any real proof to aliens currently. Scientists are still trying to figure out if aliens are even real.
you know, i think there is, bcause people say they have seen ufos. but to tell you the truth, i don't think anyon has definite proof of aliens from space.
No concrete evidence has ever been published of intelligent alien life.
Not a shred.
No.
No
they are real i have proof as well so don't say they are not real cause that would be really dumb!
Well, there are real things that appear to be flying that couldn't be identified; that's why they're called UFOs (Unidentified Flying Objects). Some are later identified. There has never yet been actual proof that UFOs come from anywhere but earth.
People have reported sightings of UFOs in France, but there is no proof of their existence.
No, but most believers don't need proof.
It is impossible to even speculate. There is no admitted proof that UFOs do exist and no hard information on propulsion.
We don't know. There is no real proof of UFO's, nor aliens. There have been rumors of the government making starships, but again, there are no proof. But in science fiction, the aliens made starships.
There are many videos and photos of flying objects. But what they are remain largly unknown. Are they run by aliens for other planets? There has yet to be definitive proof of that.
No.
There is proof of snow and Bacteria on Mars, but I'm not sure about the UFO's.
yes duhh
No. "Proof by a preponderance of the evidence" (meaning: my argument can beat up your argument) is the standard for most civil trials. "Proof beyond a resonable doubt" (meaning: unless UFOs are real we gotcha) is the standard for most criminal trials.
Most likely, but there isn't much concrete proof either way.
