How they are described
- Short, about 3 to 4 feet tall, with grey or pale skin.
- A large head, large dark almond-shaped eyes, and small or missing nose, ears and mouth.
- Thin bodies and limbs, often with long fingers.
- Communication described as telepathic rather than spoken.
Key cases
- Betty and Barney Hill (1961). Often seen as the first widely publicized abduction account with beings resembling the Greys.
- Travis Walton (1975) and the reports collected by Budd Hopkins and Dr. John Mack.
- Whitley Strieber's Communion (1987), whose cover made the image famous worldwide.
The debate
Researchers point out that the Grey image grew alongside films and television, and that hypnotic recall can shape memories. Others note how consistent many independent accounts are. The UTP records the reports as testimony; it does not treat them as proof of a particular species.
