UFO Sightings are just like the mystery of Bermuda triangle, people who have experienced it believe it exist and rest just consider it as rumors.
In popular culture, the term UFO–or unidentified flying object–refers to a suspected alien spacecraft, although its definition encompasses any unexplained aerial phenomena.UFO sightings have been reported throughout recorded history and in various parts of the world, raising questions about life on other planets and whether extraterrestrials have visited Earth. They became a major subject of interest–and the inspiration behind numerous films and books–following the development of rocketry after World War II.
According to one of the NASA astronaut who walked on the Moon aliens intervened in the Second World War to prevent a nuclear war between America and Russia.
Edgar Mitchell, who was the sixth man on the Moon, Said that US military chiefs saw alien crafts observing during their nuclear weapons tests in the New Mexico White Sands deserts in July 1945.
The astronaut turned die-hard alien believer, who walked on the Moon during the 1971 Apollo 14 mission, has regularly spoken of his believe that extraterrestrials (ETs) visit Earth, and in particular during the 1947 Roswell incident.
He even claimed they had shot down test nuclear missiles to prevent an all out nuclear battle between the US and Russia.
He said: "They wanted to know about our military capabilities.
"My own experience talking to people has made it clear the ETs had been attempting to keep us from going to war and help create peace on Earth.
"Other officers from bases on the Pacific coast told me their missiles were frequently shot down by alien spacecraft."
Mr Mitchell, 84, claims the purpose of the mission was to keep a check on our weapons to ensure it could not threaten the wider universe.
He added that alien technology was so much more advanced than ours we would be doomed if they turned hostile.
