Concerning the Chaos thing, I'd like to phrase some things better. My idea of Chaos refers to it as it appears in Hesiod's Theogeny and perhaps elsewhere. As wikipedia says:
Chaos (Greek ÏάοÏ, khaos) refers to the formless or void state preceding the creation of the universe or cosmos in the Greek creation myths, or to the initial "gap" created by the original separation of heaven and earth.
