David Vaughan Icke ( born 29 April 1952) is a British writer and public speaker, best known for his conspiracy literature. Describing himself as the most controversial speaker in the world, he is the author of 19 books and has attracted a global following that cuts across the political spectrum. His 533-page The Biggest Secret (1999) has been called "the Rosetta Stone for conspiracy junkies.
Icke combines metaphysical discussion about the nature of the universe and consciousness with conspiracy theories about public figures being satanic paedophiles, and how apparently unconnected events are in fact attempts to control humanity. He argued in The Biggest Secret that human beings originated in a breeding program run by a race of reptilians called Anunnaki from the Draco constellation, and that what we call reality is just a holographic experience; the only reality is the realm of the Absolute.
He believes in a collective consciousness that has intentionality; in reincarnation; in other possible worlds that exist alongside ours on other frequencies; and in acquired characteristics, arguing that our experiences change our DNA by downloading new information and overwriting the software. We are also able to attract experiences to ourselves by means of good and bad thoughts.
