Pseudoarchaeology—also known as alternative archaeology, fringe archaeology, fantastic archaeology, or cult archaeology—refers to interpretations of the past from outside of the archaeological science community, which reject the accepted datagathering and analytical methods of the discipline. These pseudoscientific interpretations involve the use of artifacts, sites or materials to construct scientifically insubstantial theories to supplement the pseudoarchaeologists' claims. Methods include exaggeration of evidence, dramatic or romanticized conclusions, and fabrication of evidence.
There is not one singular pseudoarchaeological theory, but many different interpretations of the past that are at odds from those developed by persons who know and understand the data. Some of these revolve around the idea that prehistoric and ancient human societies were aided in their development by intelligent extraterrestrial life, an idea propagated by those such as Swiss author Erich von Däniken in books such as Chariots of the Gods? (1968) and Italian author Peter Kolosimo. Others instead hold that there were human societies in the ancient period that were significantly technologically advanced, such as Atlantis, and this idea has been propagated by figures like Graham Hancock in his Fingerprints of the Gods (1995).
Many alternative archaeologies have been adopted by religious groups. Fringe archaeological ideas such as archaeocryptography and pyramidology have been embraced by religions ranging from the British Israelites to the theosophists. Other alternative archaeologies include those that have been adopted by members of New Age and contemporary pagan belief systems. These include the Great Goddess hypothesis, propagated by Marija Gimbutas, according to which prehistoric Europeans worshipped a single female monotheistic deity—and various theories associated with the Earth mysteries movement, such as the concept of ley lines.
