I, too, go for more of the Babylonian creation story. But before that, I came up with my own (albeit, maybe not the more serious of creation myths)....
I liked the thought of God holding a little box with a label on it that reads, "Acme Instant Universe". He takes out a little marble sized ball from the box and throws it out his door into the nothingness. It flies across the sky until it reaches a certain point and explodes (The Big Bang) and the universe suddenly appears where once there was darkness.
