Reptilians (also called reptoids, reptiloids, or draconians) are purported reptilian humanoids that play a prominent role in science fiction, as well as modern ufology and conspiracy theories. The idea of reptilians on Earth was popularized by David Icke, a conspiracy theorist who believes shape-shifting reptilian people control our world by taking on human form and gaining political power to manipulate our societies. Icke has claimed on multiple occasions that many of the world leaders are, or are possessed by, reptilians attempting to gain power to run the world.
Alien abduction narratives sometimes allege contact with reptilian creatures. One of the earliest reports was that of Ashland, Nebraska police officer Herbert Schirmer, who claims to have been taken aboard a UFO in 1967 by humanoid beings with a slightly reptilian appearance, who wore a "winged serpent" emblem on the left side of their chests.
According to British writer David Icke, 5- to 12-foot (1.5–3.7 m) tall, blood-drinking, shape-shifting reptilian humanoids from the Alpha Draconis star system, now hiding in underground bases, are the force behind a worldwide conspiracy against humanity. He contends that most of the world's leaders are related to these reptilians, including George W. Bush of the United States, and Queen Elizabeth II of the United Kingdom. Icke's conspiracy theories now have supporters in 47 countries and he frequently gives lectures to crowds of 2,500 or more. American writer Vicki Santillano ranked the notion that "Reptilian humanoids control all of us" as one of the 10 most popular conspiracy theories.
Skeptics who adhere to the psychosocial hypothesis of UFOs argue that the "Reptilians" mythos originate from V, a science fiction television miniseries (and later series) which first aired in 1983.
In V, supposedly peaceful alien "Visitors", who appear human, arrive on Earth in giant flying saucers and initiate first contact. In fact, the Visitors wear masks concealing their true shapes. In their natural form, they resemble humanoid reptiles and eat living mammals. The Visitors commence a stealth alien invasion in which they set out subtly undermining the human, and, specifically, the American way of life. The creators of the series intended this as an allegory of fascism. A remake of the series aired from 2009 to 2011.
A 1934 Los Angeles Times article may have been the origin of such beliefs. The article reported that a geophysical mining engineer claimed to have discovered subterranean labyrinths beneath Los Angeles to an underground city built by an advanced race of "Lizard People" to escape surface catastrophes some 5,000 years ago. This article, however, had remained obscure in the intervening years, even amongst consumers of conspiracy theories.
