So far as anyone knows and has proven, zero. There are no aliens known to exist, just a bunch of anecdotes, and no matter how high you stack anecdotes, they never become evidence. We hope there is other life out there, and we consider it likely. But someone has to be the first form of intelligent life in the universe, and there is no evidence that it isn't us.
The vast majority of the world's population have not seen a UFO.
UFOs are a figment of the imagination. No one has ever proven that UFOS (and we are talking about UFOs piloted by alleged aliens) actually exist.
No aliens. No spaceships.
yes there are people have seen them
Yes.... People have seen UFOs.
A number of people CLAIM to have seen aliens, or THOUGHT they had seen aliens. So far, though, there has been no proof one way or the other.
I saw a movie called " where are the aliens? " and i have to say its quiet scary by the way im 18!
We humans don't know much about these aliens, so this question has not yet been answered positively.
In area 51 and surrounding areas people say that they have seen some actives of aliens. i i have researched this and i have not found anything about area 21 and aliens.
No, no one has seen any aliens before. The "saucers" that people have seen are either figments of their imaginations or publicity stunts. There is no such thing as aliens.
There are a lot of people who believe in aliens these days, but there are about a million people per state.
Many people have claimed to but they could be just seeing things or having a dream. But some could be true but there is no proof if it is.
No, not personally. I believe that aliens are afraid of me.
No. People have speculated for years over such phenomena as the Min-Min Light and other lights seen hovering in the outback, but aliens do not live in Australia.
