There are Gods such as Zeus, Poseiden, Hades, Aris, Athena, and Aphrodite. They also believe in people called "Titans". Some titans include Gaea, Uranus, Rhea, and Crius. Greeks believe in creatures such as cyclopes and giants. Cyclopes are tall creatures that have only one eye and kill humans. Giants are abnormally tall creatures (as tall as full grown tress) that also kill humans and eat them sometimes.
