Greek Mythology is a huge subject with many gods and goddesses. Greek Mythology starts off in the beginning, the universe was just a big emptiness. Suddenly a bird appeared in this emptiness and laid an egg. Eros came from this egg. The top of the egg flew up and created Uranus. The bottom fell downward and became Gaea. Uranus and Gaea had many children, who were know as the Titans. Cronos was the chief Titan. Cronos was full of hate and did not want any children of his own to replace him as chief. So every time his wife gave birth, Cronos swallowed the baby. But when Zeus was born, his mother hid him from Cronos. After Zeus grew up he challenged his father. Cronus then vomited out all his children who were now strong adults. They banished the Titans.
