The Greeks never fully agreed who the first god was. Some claim it was Oceanus and Tethys. Even then, many believed that life began in the sea. Hesiod wrote that in the beginning there was Chaos who brought forth Gaia (Earth), Tartarus (Underworld), Eros (Desire), Nyx (Night), and Erebus (Darkness of the Underworld). Still others thought it was Night or Time that came first. Then some schmuck said that it was the four elements woven with the powers of Love and Strife. I kinda like that one.
