Senior bibliographer from the Library of Congress, Miss Lynn E. Catoe wrote the government document, UFOs AND RELATED SUBJECTS: An Annotated Bibliography, and summarizes her findings. She wrote, "A large part of the available UFO literature is closely linked with mysticism and the metaphysical. It deals with subjects like mental telepathy, automatic writing and invisible entities as well as phenomenon like poltergeist manifestation and possession. Many of the UFO reports now being published in the popular press recount alleged incidents that are strikingly similar to demonic possession and psychic phenomena that have long been known to theologians and parapsychologists."

Notice the resemblance between the frog and the alien.
"Because it is sometimes so unbelievable, the truth escapes being known." Heraclitus (500 B.C.)
