The Gods Have Landed is a comprehensive account of the religious dimension of the UFO/flying saucer experience. It examines the religious meanings attached to UFOs by the larger society as well as specific movements that claim inspiration from "Space Brothers" and other extra-terrestrial sources. It addresses the religious dimension of the phenomenon of alien abductions, particularly the impact of extra-terrestrial life on Christian theology.

Of special interest are the surveys of primary and secondary materials that make this book the indispensable reference on the subject.
