Reptilians, often referred to as Reptoids or Lizard People, are a fictional race of extraterrestrial beings that are said to resemble reptiles. They are commonly depicted in conspiracy theories as shape-shifting creatures that can disguise themselves as humans. These theories suggest that Reptilians infiltrate governments and other powerful institutions to manipulate society for their own purposes. The concept of Reptilians gained popularity in the late 20th century, particularly through the works of authors like David Icke. While there is no scientific evidence supporting the existence of Reptilians, they have become a prominent figure in popular culture, often appearing in movies, books, and television shows that explore themes of alien life and conspiracy.
