Everyone knows that there are Aliens in this world. Aliens are real and Aliens are very much here.
Greys are typically depicted as dark grey-skinned diminutive humanoid beings that possess reduced forms of, or completely lack, external human organs such as noses, ears or sex organs. Their bodies are usually depicted as being elongated, having a small chest, and lacking in muscular definition and visible skeletal structure. Their legs are shorter and jointed differently from what one would expect in a human. Their limbs are often depicted as proportionally different from a human's; their humerus and thighs are the same lengths as their forearms and shins, respectively.
Greys are depicted as having unusually large heads in proportion to their bodies. They are depicted as having no hair anywhere on the body, including the face, and no noticeable outer ears or noses, but only small openings or orifices for ears and nostrils. They are depicted as having very small mouths, and very large opaque black eyes with no discernible iris or pupil. Reports of alleged encounters state their height to be 2–4 ft tall, but may be human size.
In the 1893 article "Man of the Year Million", the well-known author H.G. Wells had envisioned the possibility of humanity transformed into a race of grey-skinned beings; who were perhaps 1 meter tall, with big heads and large, oval-shaped pitch black eyes. In his 1901 book The First Men in the Moon, Wells described Selenites (natives of the Moon) as having grey skin, big heads, and large black eyes. He also briefly describes aliens resembling Greys brought down to Earth as food for the Martians, who were the antagonist characters in his 1898 novel The War of the Worlds.
In 1933, the Swedish novelist Gustav Sandgren, using the pen name Gabriel Linde, published a science-fiction novel called Den okända faran (The Unknown Danger), in which he describes a race of extraterrestrials: "...the creatures did not resemble any race of humans. They were short, shorter than the average Japanese, and their heads were big and bald, with strong, square foreheads, and very small noses and mouths, and weak chins. What was most extraordinary about them were the eyes—large, dark, gleaming, with a sharp gaze. They wore clothes made of soft grey fabric, and their limbs seemed to be similar to those of humans. The novel, aimed at young readers, included illustrations of the imagined aliens.

In 1965 newspaper reports of the Betty and Barney Hill abduction brought Greys to international attention. The alleged abductees, Betty and Barney Hill, claimed that in 1961, alien beings had abducted them and taken them to a flying saucer or saucer-shaped spaceship. (The term "Greys" did not come into usage until many years later, but the beings described by the Hills generally fit many characteristics of the Greys.)
