The Greys are the extra terrestrial species that are most often reported by people around the world. Reports from individuals who have been in contact with the Greys vary on their intentions: some say they are kind beings-here to guide us through our evolution, while others believe they are cruel invaders intent on ruling the planet. One thing is certain, most people who have come in contact with Greys believe that they are actively abducting people on a regular basis. The Greys are reported to be abducting individuals and extracting eggs or semen to create a grey-human hybrid.

The Greys are the extra terrestrial species that are alleged to have crash-landed in Roswell, New Mexico in July 1947. As well, some researchers believe the Greys have entered into a contract with the U.S. government to trade their advanced technology for permission to abduct U.S. citizens.
