Erich von Däniken


Erich von Däniken was a leading proponent of this theory 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.

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

 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.

Shklovski 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 '60s; that repeated instances of extraterrestrial visitation to Earth were plausible; and that pre-scientific narratives can offer a potentially reliable means of describing contact with outsiders. Additionally, Shklovski 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.

In his 1979 book Broca's Brain, Sagan suggested that he and Shklovski might have inspired the wave of '70s 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." Sagan argued that while many legends, artifacts, and purported out-of-place artifacts were cited in support of ancient astronaut theories, "very few require more than passing mention" and could be easily explained with more conventional theories. Sagan also reiterated his earlier conclusion that extraterrestrial visits to Earth were possible but unproven, and perhaps improbable.

Book of Genesis and Book of Enoch

The Book of Genesis, chapter 6 verses 1–4, states:
When human beings began to increase in number on the earth and daughters were born to them, the sons of God
Sons of God
Sons of God is a phrase used in Levantine Bronze and Iron Age texts to describe the "divine council" of the major gods.- The term "sons of God" :...

The Nephilim are the offspring of the "sons of God" and the "daughters of men" in Genesis 6:4, or giants who inhabit Canaan in Numbers 13:33. A similar word with different vowel-sounds is used in Ezekiel 32:27 to refer to dead Philistine warriors....

 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)


One interpretation is that the Nephilim are the children of the "sons of God" and "daughters of humans", although scholars are uncertain. The King James Version replaces the term "Nephilim" with "giants".

expands and interprets Genesis 6:1. It explains that the "sons of God" were a group of 200 "angels" called "Watchers". Against God's wishes, these Watchers 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

s".

Some ancient astronaut theorists believe that this story is a historical account of extraterrestrials visiting Earth. In their interpretation, the "angels" are extraterrestrials and were 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.

Chuck Missler and Mark Eastman argue that modern UFOs carry the fallen angels, or offspring of fallen angels: the Nephilim of Genesis, who have now returned. They believe it was this interbreeding between the angels and humans that led to what they call “the gene pool problem.” Noah was perfect in his “generations,” that is “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.”

Von Däniken also suggests that the two angels who visited Lot
Lot (Bible)
Lot is a man from the Book of Genesis chapters 11-14 and 19, in the Hebrew Bible. Notable episodes in his life include his travels with his uncle Abram ; his flight from the destruction of Sodom, in the course of which Lot's wife looked back and became a pillar of salt; and the seduction by his...

 in Genesis 19 were not angels, but ancient astronauts. They may have used atomic weapons to destroy the city of Sodom
Sodom and Gomorrah
Sodom and Gomorrah were cities mentioned in the Book of Genesis and later expounded upon throughout the Hebrew Bible, the New Testament and Deuterocanonical sources....

. In any case, the otherworldly beings acted as if there was a time set for Sodom’s destruction. Von Däniken questioned why God would work on a timetable and why an "infinitely good Father" would give "preference to ‘favorite children,’ such as Lot’s family, over countless others."

Marc Dem completely reinterprets Genesis by claiming humanity started on another planet and that the God of the Bible is an extraterrestrial.

Book of Ezekiel
The Book of Ezekiel is the third of the Latter Prophets in the Hebrew Bible, following the books of Isaiah and Jeremiah and preceding the Book of the Twelve....

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".

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 and by Arthur W. Orton in 1961. A detailed version of this hypothesis was described by Josef F. Blumrich in his book The Spaceships of Ezekiel

Supporters contend 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.

These contentions 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, and they have speculated that with a larger workforce larger megaliths could be towed with ancient technology.

Reception

Despite the proponents' own interpretations of ancient writings and artifacts, there has yet to be found any hard evidence to support the ancient astronaut hypothesis.

Alan F. Alford, author of Gods of the New Millennium (1996), was an adherent of the ancient astronaut theory. Much of his work draws on Sitchin’s theories. However, he now finds fault with Sitchin’s theory 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.”
