List of alleged extraterrestrial beings

From Wikipedia, the free encyclopedia

This is a list of alleged extraterrestrial beings that have been reported in close encounters, claimed or speculated to be associated with "Unidentified flying objects" (UFOs) (not to be confused with the meaning of the term 'alien species' in the biological science of ecology).[1]


Flatwoods monster[2][3] Tall humanoid with a spade-shaped head.[2]
Greys[4][5] Grey-skinned humanoids, usually 1 metre (3–4 feet) tall, hairless, with large heads, black almond-shaped eyes, nostrils without a nose, slits for mouths, no ears and 3–4 fingers including thumb. Greys have been the predominant extraterrestrial beings of alleged alien contact since the 1960s.[5]
Hopkinsville goblin[6][7][8] Small, greenish-silver humanoids.[9]
Little green men[10] Diminutive green humanoids. Even though a few abductions have referred to green skin, no report has ever involved anything that would fit the classic cultural stereotype of "Little Green Men". They are included here only for cultural reference.[10]
Nordic aliens[11][12] Humanoids with stereotypical "Nordic features" (tall, blonde hair, blue eyes) and have featured in several cases of contact. It is said they are from Ancient Earth but presenting themselves as ETs in the past, they moved from living on the surface to live underground around the Himalayas area after a natural event.[13]
Cryptozoological animals and cryptobotanical plants, including those from folklore, religion (e.g. golem), mythology (e.g. dwarf (see also dwarfism); giants from Atlantis (see also gigantism), etc.), and even some reports of ghosts, poltergeists, and time travellers (alleged) Some claim that many of the allegedly real creatures from the Fortean archives (see also: Fortean Times and William R. Corliss) and related reports of anomalous phenomena[18] are actually of extraterrestrial or mixed origin, such as in the extraterrestrial hypothesis, the interdimensional hypothesis, or the cryptoterrestrial hypothesis. Sometimes these creatures are associated with the occult or with esotericism, or linked with supernatural or paranormal phenomena. Others dismiss these explanations in favor of skepticism, cultural tracking, or the psychosocial hypothesis such as in cases of mass hysteria. Some of these alleged encounters have turned out to be hoaxes or scams to boost local tourism, sell more newspapers or more fringe science books.
Reptilians and Reptiloids (sometimes spelled as reptillians)[19] Tall, scaly humanoids. Reptilian humanoid beings date back at least as far as Ancient Egypt, with the crocodile-headed river god Sobek. The Reptilian conspiracy theory has been advocated by David Icke.
Rods[20] or Skyfish Elongated visual artifacts appearing in photos and video recordings, sometimes claimed to be extraterrestrial beings. Generally thought to be caused by motion blur from flying insects.
