Information about the Grey Alien: https://en.m.wikipedia.org/wiki/Grey_alien
Grey aliens, also referred to as "Alien Greys", "Greys", "Grays" and "Roswell Greys", are extraterrestrial beings whose existence is discussed in ufological, paranormal, and New Age communities, and who are named for their unique skin color. Forty-three percent of all reported alien encounters in the United States describe Grey aliens. Such claims vary in every respect including their nature, origins (ETs, extradimensionals, time travelers, or machines), moral dispositions, intentions, and physical appearances (even varying in their skin color).[citation needed]
A composite description derived from overlap in claims would have Greys as small-bodied beings with smooth grey-colored skin, enlarged hairless head and large black eyes. The origin of the idea of the Grey is commonly associated with the Barney and Betty Hill abduction claim which took place in 1961, although skeptics see precursors in science fiction and earlier paranormal claims.
The Grey aliens are also famous from earlier depictions of the Roswell UFO incident from 1947. Some sources in UFO community describe role of grey alien race as an artificially created being used by other races as servants or even slaves used to execute tasks such as abductions and others.
