Since alien visits are not necessarily observed by us, or even if they are observed, they may not be possible to confirm, we cannot be certain how many times aliens have been on Earth, however I will say that we have no clear evidence that the Earth has ever been visited by aliens from outer space. That remains speculative.

There is no scientific evidence or consensus to suggest that aliens have ever visited Earth. While claims of alien sightings and encounters have been made, none have been substantiated by credible scientific investigation. The existence of extraterrestrial life remains an open question, but to date, there is no definitive proof of interactions between aliens and humans.

How many aliens sightings of aliens and UFOs?
There are many UFO sightings every year. Half of all Americans believe that Earth has been visited by aliens. Almost that amount believe that aliens are spying on us right now. The others are non believers. UFOs have no known connection to aliens whatsoever. They are just things in the sky the witnesses themselves could not ID. So far no aliens have been proven to exist, either. So the best answer to the above question is "zero". The reason so many people are "non-believers" is that flying saucer buffs are "non-provers"!
