Definition: A species of off-planet beings with large almond eyes and hairless gray skin. Vary in height from four feet to over six feet. Although many unpleasant experiences have been attributed to greys, more extensive research indicates they have been present on Earth for a very long time, and, in general, their activities are intended to contribute to the upgrading of our world.
Many pictures of Grey extraplanetary beings exist in the literature and on various web sites. The picture above is typical.
