Extraterrestrial refers to any object or being beyond planet Earth. Extraterrestrial beings that have been reported, are claimed to be associated with UFOs (Unidentified Flying Objects). It is also believed there are many visitors here from the other worlds who are observing our planet. Extraterrestrial Life, also called Alien Life, is life that does not originate from the earth. These as-yet-hypothetical life forms may range from simple single-celled organisms to beings with civilizations far more advanced than humanity. Although many scientists expect Extraterrestrial Life to exist yet there is no concrete evidence for its existence so far. The science of Extra-terrestrial Life is known as Exobiology.
