Ufo is an acronym for unidentified flying object, a term commonly used to describe strange aerial phenomena. Although there have been numerous sightings of UFOs throughout history, the notion that extraterrestrial beings are visiting Earth is still highly contentious. Reports of UFO sightings are often accompanied by descriptions of lights, odd shapes, and bizarre maneuvers in the sky that cannot be explained by any known aircraft or natural phenomenon. Many skeptics believe that most UFO sightings can be explained as misidentifications of terrestrial objects or natural phenomena. Others believe that some sightings are of genuine extraterrestrial craft, and some believe that some Earth governments are conducting secret research related to flying saucers.
