Proponents cite ancient mythologies to support their viewpoints based on the idea that ancient creation myths of gods who descend from the heavens to Earth to create or instruct humanity are actually representations of alien visitors, whose superior technology accounts for their reception as gods. Proponents attempt to draw an analogy to occurrences in modern times when isolated cultures are exposed to Western technology, such as when, in the early 20th century, "cargo cults" were discovered in the South Pacific: cultures who believed various Western ships and their cargo to be sent from the Gods as fulfillment of prophecies concerning their return.
Flying machines are sometimes mentioned in ancient texts; one example is the Vimanas, flying machines found in the Sanskrit epics of India. These tales range from fantastic aerial battles employing various weaponry, to the mundane relating simple technical information, flight procedure, and flights of fancy. (See also Vaimanika Shastra, a text on Vimanas supposedly "channeled" in the early 20th century.)
In the Biblical Old Testament, the Book of Ezekiel tells of a flying object seen as a fiery whirlwind which when descended to the ground gave the appearance of being made of metal. It is described among other things as a wheel within a wheel containing four occupants, "living creatures", whose likeness was that of man. The passage goes on to say that wherever the wheels went the creatures went, and when the living creatures were lifted up the wheels were lifted up. The book of Genesis(6:1-4) also tells us of such an encounter where the "sons of heaven" had intercourse with the "daughters of man" which produced the Nephilim. The apocryphal Book of Enoch tells of similar flying objects and beings, but goes further in that Enoch is taken on journeys to various corners of the Earth in the object and at one point even travels to the heavens. In several chapters of the Old Testament God is depicted as traveling as a column of smoke and/or fire and making the sound of a trumpet. These descriptions also describe Yahweh as having a physical presence, rather than an abstraction. Yahweh is described raining lightning and stones down upon the enemies of the Hebrews.
Additionally, the characteristics of the Ark of the Covenant and the Urim and Thummim are identified as suggesting high technology, perhaps from alien origins
