Their meanings typically are more about humans' place in the cosmos/world and how we should relate to each other and other beings than it is for the purpose of explanation (as scientific theory would be).
Quite agree - creation stories are often very rich in symbolism that says a lot more about the cultures and people for whom these were aimed at, and their priorities from that cultural stand point.
Some of the Egyptian creation myths, for example, can sound quite absurd - but once you understand the cultural meanings behind the symbols, you can grasp something of the logic behind them.
For example, among the Ancient Egyptians, the unique fertility of the Nile combined with the perceived movement of the sun from east to west set precedents in symbolism relating to meanings of space and time according to this. It's fascinating once you realise east = birth, yesterday, before, beginning; west = death, tomorrow, soon, ending, etc.
Overall, the closest I can come to uniting my experience of the Divine with ideas about the origins of life and universe is just to point people toward the fly-throughs of the Mendelbrot set. I can't describe my thought better than seeing that.
Ah, yes, quite agree:
The flythroughs seem to be showing something fundamentally profound, that unfortunately I'm too ape-like to be able to comprehend and describe.
