The Ancient Greeks believed that in the beginning, the world was in a state of nothingness which they called Chaos. Suddenly, from light, came Gaia (Mother Earth) and from her came Uranus (the sky) along with other old gods (called primordials) like Pontus (the primordial god of the oceans). Gaia and Uranus had 12 children, the Titans. The most important of the 12 children were Kronos and Rhea.

Gaia gave birth to some monsters called cyclops and the hundred handed ones. Uranus disgusted by the monsters threw them in Tartarus. Gaia, angered by Uranus, sought revenge on Uranus. Gaia used her son Kronos, who chopped off Uranus' genitals. Kronos threw Uranus into the ocean. From the blood of his genitals, came the goddess of love and beauty—Aphrodite.

Kronos married his sister Rhea and gave birth to 6 children, who were called the gods. Kronos, who was afraid of a prophecy delivered to him a while ago (which stated that one day his children would cut him up), swallowed each of his children each time they were born. Rhea did not like this, so she saved Zeus and gave Kronos a rock to eat instead. Zeus was raised by a goat named Amaltheia, in a mountain cave located in Crete. When Zeus was old enough, he tricked Kronos into drinking a mixture of wine and mustard. Kronos vomited up the rest of the gods, who, being immortal, had been growing up completely undigested in Kronos' stomach. Zeus and other gods then had a big war with the Titans. Zeus won with the help of the hundred handed ones and the cyclops. After they won the war Zeus cut Kronos into pieces and threw them into Tartarus.

Zeus was from then on the leader of the gods, Poseidon took over the oceans and Hades took over the Underworld. Zeus married his sister Hera and crowned her Queen of Olympus.

Men were created by the Titan Prometheus, who did not participate in the war.
