Sitchen based his ideas around a planet Nibiru, a supposed 12th planet that takes 3,600 years to orbit the sun, or something like that.
Certain artifacts and monumental constructions are claimed by von Däniken to have required a more sophisticated technological ability in their construction than that which was available to the ancient cultures who constructed them. Von Däniken maintains that these artifacts were constructed either directly by extraterrestrial visitors or by humans who learned the necessary knowledge from said visitors. These include Stonehenge, Pumapunku, the Moai of Easter Island, the Great Pyramid of Giza, the ancient Baghdad electric batteries.
Zecharia Sitchin's series The Earth Chronicles, beginning with The 12th Planet, revolves around Sitchin's interpretation of ancient Sumerian and Middle Eastern texts, megalithic sites, and artifacts from around the world. He theorizes the gods of old Mesopotamia were actually astronauts from the planet "Nibiru", which Sitchin claims the Sumerians believed to be a remote "12th planet"
Robert K. G. Temple's 1976 book, The Sirius Mystery argues that the Dogon people of northwestern Mali preserved an account of extraterrestrial visitation from around 5,000 years ago. He quotes various lines of evidence, including supposed advanced astronomical knowledge inherited by the tribe, descriptions, and comparative belief systems with ancient civilizations such as ancient Egypt and Sumer. His work draws heavily on the studies of cultural anthropologists Marcel Griaule and Germaine Dieterlen.
In their 1966 book Intelligent Life in the Universe astrophysicists I.S. Shklovski and Carl Sagan devote a chapter to arguments that scientists and historians should seriously consider the possibility that extraterrestrial contact occurred during recorded history. However, Shklovski and Sagan stressed that these ideas were speculative and unproven.
