it depends, technically UFO stands for Unidentified Flying Object. no one knows if alien spacecrafts even exist, although the possibility is pretty high, anything can be a UFO if it flys/floats through the air and you dont know what it is.
There is no reason to think UFOs are alien spacecraft, or that anything is "living in them". They're just things people see that they themselves can't identify-- that is what the U in UFO stands for, "unidentified". If they were alien spacecraft we would call them IAS, "Identified Alien Spacecraft". If you believe it then aliens.
Neither aliens nor alien spacecraft are known and proven to exist. In that sense, the answer is no. UFO means "unidentified flying object", not "alien spacecraft". If there are aliens out there on other planets, and they see something they themselves cannot identify up in the air, then in that sense there is an alien UFO.
The acronym "UFO" stands for "Unidentified Flying Object", not "Alien Spacecraft". UFO means you don't know what it is, which means you don't know it to be an alien spacecraft! An alien means someone who is from another country. It is also used to mean "person from another planet". So far, in real life, no aliens are known and proven to have come to Earth. No UFO has ever turned out to be an alien spacecraft. It's fun to pretend about such things, but taking it any further than the actual facts is like a carpenter driving nails into air-- not a lot actually gets done!

No, if by "real UFO" you mean "alien spacecraft*. No one is known and proven to have seen one of those!
No. UFOs are proof that some people have seen things in the sky that they themselves cannot identify. That is what UFO means, not *alien spacecraft*. There has never been the slightest shred of evidence that *any* UFO was an alien spacecraft, so the answer to your question is no.
Never. In real life no proof of any aliens and/or alien spacecraft even exists.
Most pictures of UFOs or Aliens are fake. So far, none of the alien photos have been shown to be anything but fake. So far, none of the UFO photos have been proven to be alien spacecraft. For some reason people call alien spacecraft, "UFOs". even though UFO just means "thing in the sky that I don't know what it is".
Ufologist. Please note that "UFO" is not an acronym for "alien spacecraft". No UFO ever, has been proven to be an alien spacecraft. In fact, at this time the existence of aliens is not proven. They seem likely, but some race in the universe has to be the first, and we don't know that we aren't it.
There are no known and proven alien spacecraft crashes in the last 20 years. Call them "alien spacecraft" because "UFO" just means "something seen in the sky that you don't know what it was". There are also no known and proven alien spacecraft crashes prior to 20 years ago. In fact, so far, we are the only known form of intelligent life in the universe. Somebody has to be first and it is beginning to look as if it is us.
Let's be clear: 'UFO' stands for Unidentified Flying Object. Any time that you see something flying and you are not entirely sure what it is, you are looking at a UFO. However, in the sense that UFO means "alien spacecraft", there have been no proven accounts of one existing.
