Where, exactly, the idea of ancient aliens building the pyramids began — and why some academics think racism lies at the heart of many extraterrestrial theories.
Capitalizing on the fervor surrounding Wells’s The War of the Worlds, astronomer and science fiction writer Garrett P. Serviss penned a quasi-sequel titled Edison’s Conquest of Mars in 1898. Serviss posited that “giants of Mars” had moved large blocks and built the Great Pyramid. He even noted that the Sphinx had Martian features. Edison’s Conquest was part of a number of science fiction works published as books or serialized in newspapers in the late 19th century which imagined alien invasions fought off by great inventors of the time. Thomas Edison was a favored hero in these science fiction fantasies much later collectively called Edisonades.
The popularization of the theory of alien architects as having a basis in science rather than consisting of only fictional musing can be attributed to Swiss author Erich von Däniken’s 1968 publication of the book Chariots of the Gods? Unsolved Mysteries of the Past. Originally published in German and subsequently translated into English, it was one of the first popularly sold books to suggest that extraterrestrial life forms, not humans, built structures associated with our ancient civilizations. In 1966, Carl Sagan and Iosif S. Shklovskii had already speculated that contact with extraterrestrials might have occurred in their book Intelligent Life in the Universe, but von Däniken took this theory to new levels.
