Grey Aliens are commonly described by ufological, paranormal, and New Age communities as slender, sexless, large-eyed, grey-colored beings who routinely visit Earth from extra-terrestrial worlds. Greys are known to sometimes abduct human beings to perform medical experiments and probe their bodies.
Ufologists believe there are at least two different types of Greys. Some claim that “taller Greys, with their reported increased authority and apparently more complex psychology, may be the only Grey type to be biologically alive and that the shorter form could be their artificially constructed robot or cyborg servants.”
