Unknown. There are millions of sightings of UFO each year. There could even be trillions of sightings. The ones on earth are at Area 51. Since we don't have access to Area 51, it is still unknown.

Are UFOs real or just a hoax?
Currently there is no firm evidence that UFOs really exist. That doesn't mean they may not be real; it just hasn't been established as a fact so far, at least in the public eye. In many individual cases, it might be a hoax - but this still isn't any proof that they don't exist. It is logical to assume, though, that as there is life on the planet Earth, there's as much a possibility of life on other planets as there is here.
