Origin[]

Grey aliens, often referred to simply as "Greys," are purported extraterrestrial beings commonly featured in UFO-related accounts and alien abduction narratives. They are typically described as humanoid entities with small, slender bodies; smooth, gray skin; disproportionately large, hairless heads; and large, black, almond-shaped eyes. Notably, they are often depicted with minimal or no external features such as noses, ears, or sex organs.
The association between Grey aliens and extraterrestrial encounters gained prominence following the 1961 Barney and Betty Hill abduction case in New Hampshire. The Hills claimed to have been taken aboard a spacecraft by beings matching the now-classic description of Greys. This account significantly influenced subsequent reports and the portrayal of alien beings in popular culture.
In ufology, Greys are frequently linked to the alleged 1947 Roswell UFO incident, where witnesses reported seeing child-sized beings with oversized heads and slanted eyes at the crash site. Over time, Greys have become a central figure in various conspiracy theories and are often cited in discussions about government cover-ups and extraterrestrial life.
The depiction of Greys has also permeated science fiction and media, becoming an archetype for intelligent non-human creatures. Their image is thought to reflect human conceptions of intelligence, with features such as large heads and eyes symbolizing advanced cognitive abilities.
