Reptilian humanoids are often described as a type of extraterrestrial being that resembles reptiles but possesses human-like characteristics. They are frequently depicted in popular culture and conspiracy theories as having green or scaly skin, sharp features, and a tall, slender build. Some believe these beings have the ability to shapeshift and are involved in secretive activities on Earth. The concept of reptilian humanoids gained popularity in the late 20th century, particularly through the works of authors like David Icke. Proponents of the theory suggest that these beings are part of a larger agenda to control humanity, often linking them to various government and elite figures. However, there is no scientific evidence to support the existence of reptilian humanoids.
