 In the book, Misraki claimed that angels from the Bible were aliens, that the Bible and other ancient texts are filled with many UFO flying saucer sightings, and that throughout human history there was intervention from extraterrestrial aliens.Misraki was also one of the first authors to suggest that apparitions may be UFO related phenomena.The Ufologist Jacques Vallée studied some of Misraki's UFO theories and visited Misraki in Paris in September 1962 to discuss them with him, in his journals Vallée described Misraki as a "deeply reflective man" and a "religious scholar".
