An unidentified flying object, or UFO, refers to
* any apparent object in the sky that is not identifiable as a known object or phenomenon.
* refers to a suspected alien spacecraft, or any unexplained aerial phenomena.
UFO raises questions about life on other planets and whether extraterrestrials have visited Earth.
Do aliens exist? Hundreds of pictures and videos of UFOs are taken every year and enthusiasts believe many of them could be proof or even a hidden conspiracy. While some have been debunked as fake, there are still dozens that have left even the experts scratching their heads and wondering if we really have been visited by creatures from another planet.
UFOs are sometimes an element of conspiracy theories in which governments are allegedly intentionally “covering up” the existence of aliens by removing physical evidence of their presence, or even collaborating with extraterrestrial beings. There are many versions of this story; some are exclusive, while others overlap with various other conspiracy theories.
