Greek mythology is a body of stories concerning the gods, heroes, and rituals of the ancient Greeks. The Greek myths exist in a world where there is a family of gods that rule over everything. The stories reveal that the Greeks believed in gods and goddesses who had control over every part of peoples lives. They believed that they had to pray to the gods for help and protection, because if the gods were unhappy with someone, then they would punish them. The Greeks had a different god for almost everything, and they imagined that the gods lived together, as a family, up on the top of Mount Olympus. The gods in Greek mythology are often portrayed as being omnipotent, omniscient, and immortal. They have the power to control the forces of nature, influence human affairs, and even grant or deny immortality. However, the gods are also often capricious and unpredictable. They can be kind and benevolent one day, and cruel and vindictive the next. The Greek Gods are very human in their instincts, desires, and temper. They are not perfect beings whom one can emulate to be a better person. The Greek Gods often display disagreeable behaviors such as tyranny, jealousy, narcissism, covetousness, psychopathy, unforgiveness, greed, and incest. The stories reveal that the Greeks used the gods to explain the unexplainable and to answer mans unanswerable questions. The gods were injected into these myths to control how people think.
