Reptilian Aliens: The History of the Lizard People Theory
1990s onward
The short version
The reptilian theory holds that shape-shifting reptile-like beings secretly control human society. In its modern form it was popularised by the British author David Icke from the 1990s. There is no evidence for it, and researchers and anti-hate organisations have described it as echoing older antisemitic conspiracy theories, a charge Icke denies.
1What happened
Reptilian beings have a long history in myth and fiction, but the modern belief that they secretly rule the world is largely the creation of David Icke, a former British sports broadcaster and Green Party spokesman. After a highly publicised spiritual awakening in 1990 and 1991, Icke began writing books about a hidden global conspiracy. Through the 1990s his theories developed until, in The Biggest Secret (1999), he argued that a race of shape-shifting reptilian beings, interbred with human bloodlines, controls governments, banks and royal families.
Icke drew on several earlier sources, including the ancient astronaut writings of Zecharia Sitchin, whose book The 12th Planet (1976) reinterpreted Mesopotamian texts as describing visitors called the Anunnaki. Specialists in ancient Near Eastern languages reject Sitchin’s translations. Icke’s speaking tours and videos drew large audiences, and the internet turned reptilian claims into a widely shared meme, with viral videos purporting to show politicians’ eyes changing shape.
The idea has also been shaped by popular fiction. The American television miniseries V (1983) depicted friendly-seeming visitors who were revealed to be reptiles disguised as humans, an image many people now associate with the theory. A 2013 Public Policy Polling survey reported that about four percent of American respondents said they believed shape-shifting reptilian people control the world, a figure pollsters caution can include joke or protest answers.
2The evidence
Believers point to videos in which a public figure’s eyes appear to flicker or distort, to claimed testimony from people who say they witnessed transformations, and to recurring serpent imagery in religion, art and heraldry, which they interpret as coded references to hidden rulers. Some also cite accounts in abduction literature of reptile-like beings seen alongside greys.
None of this material withstands scrutiny. Video distortions are consistent with compression artefacts, interlacing and lighting effects, which are common in digital footage. Testimony of transformations has not been independently verified. Serpent symbolism is found in almost every culture for well-understood reasons, including the real danger snakes posed and their association with renewal through shedding skin, and it does not point to any single hidden group.
3The official explanation
No scientific or governmental body treats the reptilian claim as a factual question requiring investigation. There is no biological basis for shape-shifting organisms, and no official UFO study, including the 2024 AARO historical report, has found evidence of extraterrestrial beings of any kind.
Researchers who study conspiracy theories treat the reptilian belief as a case study in how such theories work. The political scientist Michael Barkun, in A Culture of Conspiracy (2003), described Icke’s work as a superconspiracy that merges UFO lore, older secret society theories and new age spirituality into a single all-explaining narrative that cannot be disproved, because any lack of evidence is taken as proof of the cover-up.
4Alternative explanations
Critics, including academic researchers and anti-hate organisations, have argued that the reptilian theory echoes antisemitic conspiracy tropes about a secret group controlling banks, media and governments through hidden bloodlines. They note that Icke’s earlier book And the Truth Shall Set You Free (1995) discussed The Protocols of the Elders of Zion, a notorious forgery, and that the structure of his theory closely parallels older antisemitic myths. Icke has consistently denied being antisemitic and says his reptilians are not a code for Jewish people or any ethnic group.
Folklore gives the idea a long background. Serpent beings appear as the naga of Hindu and Buddhist traditions, as the tempting serpent of Genesis, and in pulp fiction such as Robert E. Howard’s serpent men of the 1920s. Psychologists add that conspiracy beliefs tend to flourish where people feel powerless and want a clear explanation for social problems. Believers respond that ancient serpent myths are memories of real beings, but offer no verifiable evidence.
5What remains unexplained
There is nothing about reptilian rulers that remains to be explained as a physical phenomenon: no evidence supports their existence and the claim is structured so that it cannot be tested.
What remains genuinely open is social rather than zoological. Researchers continue to study why all-encompassing conspiracy theories attract followers, how ironic and sincere belief mix online, and how old prejudices can be carried inside apparently new stories. The reptilian theory is a clear example of all three, which is why it continues to attract academic attention decades after it first appeared.
