In Intelligent Life in the Universe (1966) astrophysicists Iosif Shklovsky [Shklovskii] and Carl Sagan devote a chapter to the argument that scientists and historians should seriously consider the possibility that extraterrestrial contact occurred during recorded history; however, Shklovskii and Sagan stressed that these ideas were speculative and unproven.[20] Shklovskii and Sagan argued that sub-lightspeed interstellar travel by extraterrestrial life was a certainty when considering technologies that were established or feasible in the late 1960s;[21] that repeated instances of extraterrestrial visitation to Earth were plausible;[22] and that pre-scientific narratives can offer a potentially reliable means of describing contact with aliens.

Sagan illustrates this hypothesis by citing the 1786 expedition of French explorer Jean-François de Galaup, comte de La Pérouse, which made the earliest first contact between European and Tlingit cultures. The contact story was preserved as an oral tradition by the preliterate Tlingit. Over a century after its occurrence it was then recorded by anthropologist George T. Emmons. Although it is framed in a Tlingit cultural and spiritual paradigm, the story remained an accurate telling of the 1786 encounter. According to Sagan, this proved how "under certain circumstances, a brief contact with an alien civilization will be recorded in a re-constructible manner. He further states that the reconstruction will be greatly aided if 1) the account is committed to written record soon after the event; 2) a major change is effected in the contacted society; and 3) no attempt is made by the contacting civilization to disguise its exogenous nature."[23]

Additionally, Shklovskii and Sagan cited tales of Oannes, a fishlike being attributed with teaching agriculture, mathematics, and the arts to early Sumerians, as deserving closer scrutiny as a possible instance of paleocontact due to its consistency and detail.[24]

In his 1979 book Broca's Brain, Sagan suggested that he and Shklovskii might have inspired the wave of 1970s ancient astronaut books, expressing disapproval of "von Däniken and other uncritical writers" who seemingly built on these ideas not as guarded speculations but as "valid evidence of extraterrestrial contact."[25] Sagan argued that while many legends, artifacts, and purported out-of-place artifacts were cited in support of ancient astronaut hypotheses, "very few require more than passing mention" and could be easily explained with more conventional hypotheses. Sagan also reiterated his earlier conclusion that extraterrestrial visits to Earth were possible but unproven, and improbable.[26]

According to Erich von Däniken, the Sarcophagus lid of Pacal the Great represents an "ancient astronaut" ascending to the stars in his spaceship.

Erich von Däniken was a leading proponent of this hypothesis in the late 1960s and early 1970s, gaining a large audience through the 1968 publication of his best-selling book Chariots of the Gods? and its sequels.

According to von Däniken, certain artifacts require 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, and the ancient Baghdad electric batteries.

The so-called "Helicopter hieroglyphs", at Abydos, Egypt, which are argued to depict flying craft

Von Däniken writes that ancient art and iconography throughout the world illustrates air and space vehicles, non-human but intelligent creatures, ancient astronauts, and artifacts of an anachronistically advanced technology. Von Däniken also states that geographically separated historical cultures share artistic themes, which he argues imply a common origin. One such example is von Däniken's interpretation of the sarcophagus lid recovered from the tomb of the Classic-era Maya ruler of Palenque, Pacal the Great. Von Däniken writes that the design represented a seated astronaut. The iconography and accompanying Maya text, however, identifies it as a portrait of the ruler himself with the World Tree of Maya mythology.

The origins of many religions are interpreted by von Däniken as reactions to encounters with an alien race. According to his view, humans considered the technology of the aliens to be supernatural and the aliens themselves to be gods. Von Däniken states that the oral and written traditions of most religions contain references to alien visitors in the way of descriptions of stars and vehicular objects travelling through air and space. One such is Ezekiel's revelation in the Old Testament, which Däniken interprets as a detailed description of a landing spacecraft (The Spaceships of Ezekiel).

Von Däniken's hypotheses became popularized in the U.S. after the NBC-TV documentary In Search of Ancient Astronauts hosted by Rod Serling, and the film Chariots of the Gods.

Critics argue that von Däniken misrepresented data, that many of his claims were unfounded, and that none of his core claims have been validated.[27] In particular the Christian creationist community is highly critical of most of von Däniken's work. Young Earth creationist author Clifford A. Wilson published Crash Go the Chariots in 1972 in which he attempted to discredit all the claims made in Chariots of the Gods.[28]

In Chariots of the Gods?, regarding the Nazca Lines, von Däniken states that "Seen from the air, the clear-cut impression that the 37-mile long plain of Nazca made on me was that of an airfield."[29] Considering he was in the process of finding evidence of ancient aliens, von Däniken exhibits confirmation bias, as he doesn't consider the Nazca Lines to be man-made until after the publication of Chariots of the Gods?. This etic perspective that he presents could be easily accepted by a reader familiar with air travel, and an undeveloped knowledge of the nature of the geoglyphs. Furthermore, since the majority of readers of Chariots of the Gods? are not educated in viewing artifacts from ancient civilizations, their interpretations are highly subject to von Däniken's opinions of the artifacts. Kenneth L. Feder argues a reader seeing the Nazca Lines for the first time in a book about aliens would be much more likely to associate those features with extraterrestrial origins, rather than from a civilization that existed on Earth.[30]

In 1970, von Däniken admits that the Nazca markings "could have been laid out on their gigantic scale by working from a model using a system of coordinates."[31]

Zecharia Sitchin's series The Earth Chronicles, beginning with The 12th Planet, revolves around Sitchin's unique interpretation of ancient Sumerian and Middle Eastern texts, megalithic sites, and artifacts from around the world.[32][33] He hypothesizes that the gods of old Mesopotamia were astronauts from the planet "Nibiru", which Sitchin states the Sumerians believed to be a remote "12th planet" (counting the Sun, Moon, and Pluto as planets) associated with the god Marduk. According to Sitchin, Nibiru continues to orbit our sun on a 3,600-year elongated orbit. Modern astronomy has found no evidence to support Sitchin's ideas.[32]

Sitchin argues that there are Sumerian texts which tell the story that 50 Anunnaki, inhabitants of a planet named Nibiru, came to Earth approximately 400,000 years ago with the intent of mining raw materials, especially gold, for transport back to Nibiru. With their small numbers they soon grew tired of the task and set out to genetically engineer laborers to work the mines. After much trial and error they eventually created Homo sapiens sapiens: the "Adapa" (model man) or Adam of later mythology. Sitchin contended the Anunnaki were active in human affairs until their culture was destroyed by global catastrophes caused by the abrupt end of the last ice age some 12,000 years ago. Seeing that humans survived and all they had built was destroyed, the Anunnaki left Earth after giving humans the opportunity and means to govern themselves. Sitchin's work has not received mainstream scholarly support and has been roundly criticized by professionals that have reviewed his hypotheses. Semitic languages scholar Michael S. Heiser says that many of Sitchin's translations of Sumerian and Mesopotamian words are not consistent with Mesopotamian cuneiform bilingual dictionaries, produced by ancient Akkadian scribes.[34][35][36]

Alan F. Alford, author of Gods of the New Millennium (1996), was an adherent of the ancient astronaut hypothesis. Much of his work draws on Sitchin's hypotheses. However, he now finds fault with Sitchin's hypothesis after deeper analysis, stating that: "I am now firmly of the opinion that these gods personified the falling sky; in other words, the descent of the gods was a poetic rendition of the cataclysm myth which stood at the heart of ancient Near Eastern religions."[37]

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 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.[38]

His conclusions have been criticized by scientists, who point out discrepancies within Temple's account, and suggested that the Dogon may have received some of their astronomical information recently, probably from European sources, and may have misrepresented Dogon ethnography.[39][40][41]

Various new religious movements including some branches of theosophy, Scientology, Raëlism, and Heaven's Gate believe in ancient and present-day contact with extraterrestrial intelligence. Many of these faiths see both ancient scriptures and recent revelations as connected with the action of aliens from other planetary systems. Psychologists have found that UFO religions have similarities which suggest that members of these groups consciously or subliminally associate enchantment with the memes of science fiction.[42]

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 representations of alien visitors, whose superior technology accounts for their perception as gods. Proponents draw an analogy to occurrences in modern time 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.[44]

The ancient Sumerian myth of Enûma Eliš, inscribed on cuneiform tablets and part of the Library of Ashurbanipal, says humankind was created to serve gods called the "Annunaki". Hypothesis proponents believe that the Annunaki were aliens who came to earth to mine gold for their own uses. According to the Enuma Elish story, the Annunaki realized mining gold was taking a toll on their race, and then created the human race as slaves.[45]

In Hindu mythology, the gods and their avatars travel from place to place in flying vehicles called Vimana. There are many mentions of these flying objects in the Ramayana, which used by the Lankan king Ravana from Sri Lanka dates to the 5th or 4th century BCE. Below are some examples:

From Book 6, Canto CXXIII: The Magic Car:[46]

From Book 6, Canto CXXIV: The Departure:[46]

Erich von Däniken discusses the Ramayana and the vimanas in Chapter 6 of Chariots of the Gods? suggesting that they were "space vehicles". To support his hypothesis, he offers a quotation which he says is from an 1889 translation of the Mahabharata by C. Roy: "Bhima flew with his Vimana on an enormous ray which was as brilliant as the sun and made a noise like the thunder of a storm".[47][48]

The Book of Genesis, Chapter 6 verses 1-2 and 4, states:

When human beings began to increase in number on the earth and daughters were born to them, the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose.
...
The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them.
— Genesis 6:1–4 (New International Version)

Many Christians consider these groups to be the different families of Adam and Eve's children. Another interpretation is that the Nephilim are the children of the "sons of God" and "daughters of humans", although scholars are uncertain.[49] The King James Version translates "Nephilim" as "giants" (or Gibborim). Ancient Astronaut proponents argue that Adam and Eve ate of the forbidden fruit in order "to be godlike", and this was the first step in human evolution.

The first part of the apocryphal Book of Enoch expands and interprets Genesis 6:1: that the "sons of God" were a group of 200 "angels" called "Watchers", who descended to Earth to breed with humans. Their offspring are the Nephilim, "giants" who "consumed all the acquisitions of men". When humans could no longer sustain the Nephilim, they turned against humanity. The Watchers also instructed humans in metallurgy and metalworking, cosmetics, sorcery, astrology, astronomy, and meteorology. God then ordered the Watchers to be imprisoned in the ground, and created the Great Flood (or the numerous Deluge myths) to rid Earth of the Nephilim and of the humans given knowledge by the Watchers. To ensure humanity's survival, Noah is forewarned of the oncoming destruction. Because they disobeyed God, the book describes the Watchers as "fallen angels".[50]

Some ancient astronaut proponents argue that this story is a historical account of extraterrestrials visiting Earth, called Watchers because their mission was to observe humanity. Some of the extraterrestrials disobeyed orders; they made contact with humans, cross-bred with human females, and shared knowledge with them. The Nephilim were thus half-human-half-extraterrestrial hybrids.[51]

Chuck Missler and Mark Eastman argue that modern UFOs carry the fallen angels, or offspring of fallen angels, and that "Noah's genealogy was not tarnished by the intrusion of fallen angels. It seems that this adulteration of the human gene pool was a major problem on the planet earth".[52]

Von Däniken also suggests that the two angels who visited Lot in Genesis 19 were ancient astronauts, who used atomic weapons to destroy the city of Sodom.[53]

Marc Dem reinterprets the Book of Genesis by writing that humanity started on another planet and that the God of the Bible is an extraterrestrial.[54]

An engraved illustration of Ezekiel's 'vision' (1670)

In the Old Testament, Chapter 1 of the Book of Ezekiel recounts a vision in which Ezekiel sees "an immense cloud" that contains fire and emits lightning and "brilliant light". It continues: "The center of the fire looked like glowing metal, and in the fire was what looked like four living creatures". These creatures are described as winged and humanoid, they "sped back and forth like flashes of lightning" and "fire moved back and forth among the creatures". The passage goes on to describe four shiny objects, each appearing "like a wheel intersecting a wheel". These objects could fly and they moved with the creatures: "When the living creatures moved, the wheels beside them moved; and when the living creatures rose from the ground, the wheels also rose".[55]

In Chapter 4 of Chariots of the Gods?, entitled "Was God an Astronaut?", von Däniken suggests that Ezekiel had seen a spaceship or spaceships; this hypothesis had been put forward by Morris Jessup in 1956[56] and by Arthur W. Orton in 1961.[57] A detailed version of this hypothesis was described by Josef F. Blumrich in his book The Spaceships of Ezekiel (1974).[58]

The characteristics of the Ark of the Covenant and the Urim and Thummim have been said to suggest high technology, perhaps from alien origins.[59]

Robert Dione and Paul Misraki published books in the 1960s describing the events in the Bible as caused by alien technology.[60][61] Barry Downing, a Presbyterian minister, wrote a book in 1968 arguing that Jesus was an extraterrestrial, citing John 8:23 and other biblical verses as evidence.[62]

Some ancient astronaut proponents such as Von Däniken and Barry Downing believe that the concept of hell in the Bible could be a real description of the planet Venus brought to Earth by extraterrestrials showing photos of the hot surface on Venus to humans. Proponents of the hypothesis state that 'God' and 'Satan' were aliens that disagreed on whether or not human beings should be allowed the information that is offered by the tree of knowledge. David Childress, a leading proponent of ancient astronaut creation hypothesis, compares this story to the Greek tale of Prometheus, who gave mankind the knowledge of fire. Ancient Astronaut proponents believe the biblical concept of Satan is based on a misunderstood visit by extraterrestrials. Erich von Däniken posited that the descendants of extraterrestrials had children with hominids, and this was referred to in the Bible as the "Original sin." Von Däniken believes that the biblical great flood was punishment after an extraterrestrial 'God' discovered that earthbound, fallen angels were mating with ape-like early humans.[63]

Childress and others have written that the passage in the Book of Invasions describing the arrival of the Tuatha Dé Danann in Ireland, records "the arrival of aliens in spacecraft with cloaking devices" at Slieve Anierin. The text states “so that they were the Tuatha De Danand who came to Ireland. In this wise they came, in dark clouds. They landed on the mountains of Conmaicne Rein in Connacht and they brought a darkness over the sun for three days and three nights".[64]

Ancient astronaut proponents believe Hopi cave drawings of Kachinas (spirit beings) found in the desert link the origins of the Hopi and Zuni tribes with "star people". They point to similar etchings elsewhere as evidence that extraterrestrials visited many different ancient civilizations.

Other artistic support for the ancient astronaut hypothesis has been sought in Palaeolithic cave paintings. Wondjina in Australia and in the Rock Drawings in Valcamonica, in Italy (seen above) are said to bear a resemblance to present day astronauts.[65] Supporters of the ancient astronaut hypothesis sometimes argue that similarities such as dome shaped heads, interpreted as beings wearing space helmets, prove that early man was visited by an extraterrestrial race.[66]

More support of this hypothesis draws upon what are said to be representations of flying saucers and other unidentified flying objects in medieval and renaissance art.[67]

A large geoglyph near the Nazca Lines, thought by some to represent an astronaut

The ancient Nazca Lines are hundreds of huge ground drawings etched into the high desert of southern Peru. Some are stylized animals and humanoid figures, while others are merely straight lines hundreds of meters long. As the figures were made to be seen from a great height, they have been linked with the ancient astronaut hypothesis. In the 1970s, the pseudohistorical writer Erich von Däniken popularized a notion that the Nazca lines and figures could have been made "according to instructions from aircraft" and that the longer and wider lines might be runways for spacecraft. According to archaeologist Kenneth Feder, Von Däniken's extraterrestrial interpretation is not supported by any evidence. Feder wrote that "the lines are interpreted by archaeologists as ceremonial pathways of the ancient Nazca people; they were used precisely in this way in the fairly recent past."[68]

Joe Nickell of the University of Kentucky was able to re-create one of the figures using only wooden stakes and string.[69]

Proponents of the ancient astronauts idea say some artifacts discovered in Egypt (the Saqqara Bird) and Colombia-Ecuador are similar to modern planes and gliders.[70] These artifacts have been interpreted by mainstream archaeologists, however, as stylized representations of birds and insects.

Ahu Tongariki near Rano Raraku; ancient astronaut proponents state that the stone structures were built by (or with the help of) extraterrestrials

Proposed evidence for ancient astronauts includes the existence of ancient monuments and megalithic ruins such as the Giza pyramids of Egypt, Machu Picchu in Peru, or Baalbek in Lebanon, the Moai of Easter Island and Stonehenge of England.[71] Supporters say that these stone structures could not have been built with the technical abilities and tools of the people of the time and further argue that many could not be duplicated even today. They suggest that the large size of the building stones, the precision with which they were laid, and the distances many were transported leaves the question open as to who constructed these sites.

These ideas are categorically rejected by mainstream archeology. Some mainstream archeologists have participated in experiments to move large megaliths. These experiments have succeeded in moving megaliths up to at least 40 tons,[72][73] and part have speculated that with a larger workforce larger megaliths could be towed with the use of known ancient technology.[74]

A physiologically manipulated Paracas skull (housed at the Museo Regional de Ica in Peru).

A number of ancient cultures, such as the ancient Egyptians and some Native Americans, artificially lengthened the skulls of their children. Some ancient astronaut proponents propose that this was done to emulate extraterrestrial visitors, whom they saw as gods.[75][76] Among the ancient rulers depicted with elongated skulls are pharaoh Akhenaten and Nefertiti. It has been pointed out that the Grey aliens, as described by many alien abductees, have similarly shaped heads.[75] In the program Ancient Aliens it was suggested that the owners of the biggest of the lengthened skulls may be human-extraterrestrial hybrids.[75]
