Answer:
Grey aliens, also referred to as Zeta Reticulans, Roswell Greys, or Grays, are purported extraterrestrial beings. According to journalist C. D. B. Bryan, seventy-three percent of all reported alien encounters in the United States describe Grey aliens, a significantly higher proportion than other countries.[1]:68 Such claims vary widely, but typically Greys are described as being human-like with small bodies with smooth grey-colored skin, enlarged hairless heads, and large black eyes. The Barney and Betty Hill abduction claim, which purportedly took place in New Hampshire in 1961, popularized Grey aliens. There are precursor figures described in science fiction and similar descriptions appeared in early accounts of the 1947 Roswell UFO incident.
The Grey alien has emerged as an archetypal image of an intelligent non-human creature and extraterrestrial life in general, as well as an iconic trope of popular culture in the age of space exploration.
