UFO religions are groups that deal with alleged communication between humans and extraterrestrial beings. Proponents often argue that most major religions are already based on the concept of a supernatural being in heaven. Forms of communication include telepathy and astral projection. Groups often believe that humanity can be saved after being educated by the aliens as to how to improve society. Alien abduction belief can lead to formation of a UFO religion. I AM Religious Activity, founded in 1930 by Guy Ballard, is seen, according to one author, as the first UFO Religion, though Aetherius Society founded by George King has also been given this distinction. Scholars identify the 1947 Roswell incident as a key event within the history of UFO spirituality. Melodie Campbell and Stephen A. Kent describe Heaven's Gate and Order of the Solar Temple as among the most controversial of the UFO belief groups. Scientology is seen by scholars as a UFO religion, due to its Xenu cosmogony and the presence of Space opera in Scientology doctrine.
