Alien Species

Grey aliens, sometimes known as Zeta Reticulans, Grays, or simply Greys, are by far the most commonly reported species involved in UFOlogical cases. Named for the coloration of their skin, these sapient humanoids have gathered fame and attention from researchers thanks to such infamous incidents as the Roswell UFO crash of 1947 and the Barney and Betty Hill abduction case in 1961; and their image has found its way into popular imagination and mass media to represent the archetypal, flying saucer-using, memory-erasing alien visitor who abducts subjects to study them.


Grey aliens, called Zeta Reticulans since the Hill abduction case, are commonly reported in UFO research. Named for the coloration of their skin, these sapient humanoids have gathered fame and attention from The Shaver Mysteries (1941) by Richard Sharpe Shaver, The Roswell Incident (1980) by Moore and Berlitz, Crash at Corona (1992) by Berliner and Friedman, and The Day After Roswell (1996) by Philip J. Corso. Their image has found its way into popular imagination and mass media to represent the archetypal, flying saucer-using, memory-erasing alien visitor who abducts subjects to study them.

In actual Fortean theories, the relationship between Greys and other races such as Reptoids is usually more complex, although it's frequently believed that the Greys themselves might be both reptilian and genetically-engineered in origin, and that they're employed; or in some sources explicitly enslaved; to act as a researching workforce and do the other race's bidding. Conversely, alternate ideas abound, including some picturing the Greys as benevolent, time-traveling descendants of Humans whose main purpose is to monitor and guide the development of their ancestors.


In the majority of UFO cases, the Greys have been consistently described as short, thin humanoids with grey and hairless skin and a conspicuously large cranium. Their eyes are large, black and almond-shaped, and their facial features are restricted to a pair of small slits in the place of the nose, and a small mouth. Their fingers are usually long and dexterous. Their bodies are proportionally small, and they don't appear to have genitals, which is noticeable due to the fact that they don't wear clothes. In some cases, they have been reported as capable of telepathy.

The body of Greys are more or less considered a vessel for higher dimensional beings to act in a lower density environment like the earth. An Is-Be in a Grey body can leave or invade this vessel according to their will much like an avatar. It is mostly designed to be a tool for example to steer spaceships, like an interface between an Is-Be and a machine. An Is-Be can control none, one or even more Grey vessels at the same moment. There are a couple of different alien races who use Grey bodies to focus energy in lower densities.


Hill abduction[]

The Hill abduction involved the abduction of Barney and Betty Hill on September 19 to 20, 1961. The Hills underwent hypnosis on January 4, 1964 in which they each described their own unique abduction experience.

Skeptics discredit what the Hills witnessed by saying that they were influenced by the The Outer Limits television show; that Betty concocted her "Grey" descriptions from the alien being shown in "The Bellero Shield", an episode that first aired on 10 February 1964. The airing of the show happened one month after the Hill's underwent their first hypnosis session.

Hypnosis sessions were conducted by Benjamin Simon. Sessions lasted until June 6, 1964. At the end of each session, Simon noted amnesia. To secure his career and ensure that the Hill case did not taint his reputation, Simon had discredited everything the Hill's saw and wrote in the journal Psychiatric Opinion, that what the Hills experienced was just a mere fantastical psychological aberration.

The notion that Hill's abductors came from Zeta Reticuli was first proposed by Marjorie Fish of Oak Harbor, Ohio, in 1968, based on her conclusions about Betty Hill's star map, drawn from hypnosis. Since then, the idea that Greys come from Zeta Reticuli has entered the popular conscious. Zetas were never thought to be connected to Roswell prior to 1968.


Dante Santori[]

Dante Santori posted an electronic file (PDF), online, called The Alien Races Book in 2014. Santori claims that the contents of the file were copied from a real physical book maintained by a Ukranian official who retired to Portugal. The contents were translated from Russian to English over a period of a few years, during a time when Google Translate was just launched and not effective until ten years after its launching.

Santori lists several Grey types in his electronic book. All of the images presented were supplanted by Santori, as no original images were provided. All images come from media or movies to best represent the alien race type depicted. Some Grey types listed:

  • Akart, who revere Sextans constellation and who was sighted in Brazil, 1996. The abduction of Artur Berlet is one of the most famous Akart cases.
  • Allgruulk/Al-Gruualix (Al gräulich, Arabic-German, meaning "The greyish, ghoulish, horrid"), are "builder" Greys who promote transgenderisation. According to Santori, they revere the Luminous Giant Star, Deneb Kaitos Shemali. This is a pun for their interests in "she-mali" or "she-male", which is part of the Anunnaki "sex cultivation" programme promoted by Pleyadians (Worshipers of the ancient chaos god—Erra).
  • Graysli, who revere the Virgo zodiac and who have influenced the building of Djoser Pyramid.
  • Lang, who have three major colonies and conduct mass abductions. They revere the celestial arrangement in the modern day Coma Berenices constellation.
  • Moovian or Molochian (Bovine headed), who revere Vulpecula ("little fox") constellation, have at least fourty colonies and engage in governmental "agreements" which allow them to abduct humans with government support, shielded by "coverups". In ancient times, there were no coverups. Everyone complied with virgin and/or child sacrifices to appease the Gods.
  • Solipsi Rai, a two billion year old race who revere constellation Cygnus and whose leader is Ymartyyn
  • Tykut, a race created by the Maitre (Anunnaki) to be used as slaves (Igigi) and carry out abductions (of humans).
  • Zeta Reticulans who revere the Net constellation (a nomenclature pun for harvesting mass human abductions like a "fisherman's net"). They are allied with the Anunnaki who are known to have installed "Zetas" as Pharoahs in Egypt. Zeta is the sixth letter in the Greek alphabet, like 666.
