Reptilians, often referred to as reptoids or lizard people, are a popular figure in conspiracy theories. They are described as humanoid creatures with reptilian features, believed by some to be capable of shapeshifting. Proponents of these theories claim that Reptilians infiltrate human society, often taking on the appearance of influential figures. The concept of Reptilians gained traction 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 remain a fascinating topic in popular culture and discussions about extraterrestrial life.
