"Lizard people" is a term often used to describe a conspiracy theory suggesting that shape-shifting reptilian aliens secretly control the world. Proponents of this theory claim that these beings can disguise themselves as humans and are involved in politics, media, and other influential sectors. The idea of lizard people gained popularity through various media, including books and television shows. Notably, the theory was popularized by conspiracy theorist David Icke, who argues that these reptilian beings are part of a larger agenda to manipulate humanity. Despite its prevalence in popular culture, there is no scientific evidence supporting the existence of lizard people.
