1) The Greek creation myth describes the origins of the universe from nothingness and the first gods and beings that emerged, including Gaia, Uranus, and their monstrous children.
2) Gaia plotted against Uranus for hiding their monstrous children and helped their son Kronos kill Uranus, allowing Kronos to become the new king of the sky.
