Earth is the only planet known to have life on it, so obviously Earth is the only known place in the universe that could have UFO sightings. It is important to remember that "UFO" just means "I don't know what that is". It does *not* mean "Alien spacecraft". That is a very unlikely answer to what UFOs are. There is no reason to think UFOs are anything other than a misidentification of known phenomena.
