History of alien-human interactions
Alien–human interactions on Earth are alleged to reach back into pre-glacial antiquity, beginning with the Anunnaki arrival from the Nibiru system and continuing through Sumer, Atlantis, the Greada Treaty of 1954, and the modern era of secret space programs — with different extraterrestrial species said to have played dominant roles at different periods.
Pre-historical and ancient period
The Anunnaki, a reptoid species from the Nibiru system, arrived on Earth and established rulership over existing Reptilian populations and early hominids. They genetically engineered a human slave class to mine gold and other resources, creating what is interpreted as the "missing link" in Terran evolutionary records. The Kuri (Xi Orionis), a bird-featured humanoid species affiliated with the Anunnaki, were directly involved in altering the Terran human genome during this same period.
The Nommo, amphibian beings from the Sirius B system, made contact with early Terran civilizations approximately 5,000 years ago — with Sumer, Babylon, Acadia, Egypt, and the Dogon among those visited — before withdrawing under pressure from the Alpha Draconian Empire.
The Ramay (Capella) established contact with ancient Terran civilizations and are credited as the founders of Mayan astronomical knowledge; they departed when the Maya were at their cultural apogee.
The Telosii colonization and inner Earth withdrawal
The Telosii, an ancient colony from Alpha Centauri B 4 (Selosii), settled on Earth before the last Ice Age. After their Atlantic civilization was destroyed, they migrated underground to form the Agarthan network, disconnecting from the Galactic Federation of Worlds in the process.
20th century: early contact and technology transfers
In the 1940s, a Pleiadian scientist named Thor — sent by the GFW — spent time with the U.S. government teaching hyper-space travel in order to accelerate Terran technological development ahead of the growing Alpha Draconian Empire threat.
Do-Hu Grey motherships established orbital and undersea presence beginning in 1953–1957, with their largest facility positioned near Easter Island.
The Emerther (Council of Five, Tau Ceti) made formal contact with world governments in 1954 on behalf of the Council of Five, warning against the Do-Hu and the Draco reptilians — and were not listened to.
Pre-Eisenhower secret treaties
Laura Eisenhower, great-granddaughter of President Eisenhower, has described an earlier sequence of secret alien-government treaties predating the 1954 Greada Treaty. During Franklin D. Roosevelt's presidency (1933–1945), several species of Grey aliens contacted all major world governments, and initial secret treaties were established — agreements that involved supplying numbers of human adults and children to the aliens in exchange for advanced technology including spacecraft blueprints, zero-point energy technology, and weaponry. According to this account, the earliest deals establishing the abduction and experimentation framework involved Winston Churchill, Aleister Crowley, and Adolf Hitler, with the alien technology trade beginning under Churchill's coordination during World War II.
The Greada Treaty (1954)
In 1954, President Eisenhower met simultaneously with the Galactic Federation of Worlds (whose offer of assistance was refused) and then with the Do-Hu Grey delegation. The Greada Treaty was signed with the Do-Hu, granting permission for limited genetic study of humans in exchange for technology. The treaty was a cover mechanism by the Alpha Draconian Empire to establish legal protection for their subsequent abduction operations.
Post-1954: expanding underground operations
Following the Greada Treaty, abduction operations rapidly expanded from a promised few hundred cases to millions. The Alpha Draconian Empire, Maytrei, and other species joined what had begun as a Do-Hu program, and underground joint facilities including Dulce Base became centers for hybridization, mind control, and soul-scalping operations.
Post-1954: Enki's scientists and the preservation of ancient knowledge
Following Enki's defeat by Enlil after the Great Flood and his departure from the Sol system, a group of four Anunnaki geneticists who were scientists rather than warriors chose not to leave with him. These scientists went into stasis in hidden chambers near the Halls of Records sites — locations including one in Florida beside a Tree of Life and another believed to be in India — determined to preserve ancient knowledge and technology until humanity could evolve sufficiently and Enki return: "When Enki left, Enki left some scientists on Earth to take care of humanity and to make sure that certain knowledge would be hidden in sacred places, but I think we can safely call these places the Halls of Records." These stasis giants — identified as Sleeping Giants — remained undiscovered in deep underground chambers, representing Enki's contingency against the total loss of antediluvian civilization, to be awakened when the time of Enlil's defeat arrived.
Scholarly and alternative perspectives on the ancient period
Michael Cremo, author of Forbidden Archaeology, distinguishes his position from Sitchin's while accepting the broader principle of extraterrestrial involvement: "Extraterrestrials, perhaps in the guise of gods or goddesses, were having something to do with our presence as human beings on this planet. That is something that I accept. It's totally reasonable." Cremo further accepts the possibility of a series of extraterrestrial interventions across hundreds of thousands or millions of years: "You accept the idea that extraterrestrials like the Anunnaki intervened at some point and genetically tinkered with whatever kind of hominids they found there to upgrade them, splicing in their genetics, that there could have been a series of extraterrestrial interventions over the course of hundreds of thousands or millions of years."
Cremo's Forbidden Archaeology presents documentary archaeological evidence for modern human fossils and artifacts dating back millions of years — far preceding the 300,000-year creation date suggested by Anunnaki texts — arguing that a process of "knowledge filtration" in mainstream academia systematically excludes any discovery that does not conform to the accepted Darwinian evolutionary timeline. Evidence of modern humans coexisting with various hominid species across millions of years suggests either that the Anunnaki's genetic project was itself one episode in a much longer series of extraterrestrial interventions, or that modern humans pre-dated the Anunnaki and the Sumerian texts record only the most recent phase of a much longer alien-human contact history. The Puranic tradition, in Cremo's view, corroborates the long timeline: the Vedas describe 400,000 humanoid species scattered throughout the cosmos — consistent with a universe in which multiple rounds of human-like seeding across deep geological time would not be remarkable.
