"I’d say that UFO beliefs are fuelled by a “secular theology” where people look for greater meaning to the universe and our relationship with it. The theme is that the aliens flying the UFOs pay attention to us, worry about our misdeeds (as evident in alleged sighting of UFOs hanging around nuclear power plants) and want to help raise us to a higher level of existence. This is simply a post-industrial age version of ages old stories of visitation by angels, demons, and other imaginary spirits."
