UFO religion
A UFO religion, also called a UFO cult or flying saucer cult, is any religion in which the existence of extraterrestrial (ET) entities and communication with them is a core belief. Typically, adherents of such religions believe the ETs to be interested in the welfare of humanity which either already is, or eventually will become, part of a pre-existing ET civilization. These religions have their roots in the tropes of early science fiction (especially space opera) and weird fiction writings, in ufology, and in the subculture of UFO sightings and alien abduction stories. Some historians consider the Aetherius Society, founded by George King, to be the first UFO religion, while others consider it to be "I AM" Activity.
