So few sightings are actually reported, there is no way to know that answer.
first of all ik they exist because I SAW ONE I WITH MY OWN EYES! there are even youtube videos on them that proves they exist it was realy freakty that i saw a ufo at school nad i was the only one who saw it..
We cannot know, they have been observed since ancient times
"UFO" does not mean alien spaceship. So far there is no scientific reason to think even one alien spaceship has ever landed on Earth. UFO just means "I saw something in the sky and I personally don't know what it was."
Not that I know of.They went to the moon to experiment, and also to be the first country (USA) on the moon. :D
In his basement, high....
That would be before written history. We can't know who the first person was that saw something flying and couldn't tell what it was.
Many people claim to have seen UFOs.
I think it all started in 1200, because I remember that I read something about the first man from Scotland that saw a UFO.
I saw one 3 days ago.
A UFO
wasnt it sneaky sound system?
i think this was a UFO sighting, i was driving home when i saw a dark blue triangle in the sky, this was on May 11 Saturday, at about 1:00 PM, 2011. i thought it was a kite at first but it was going so fast and it was so big that there was no way it was a kite. a UFO? i thought to myself. a minute after it disappeared a helicopter went in its direction. then i wondered if the government saw the UFO and tried to catch it.
