What it boils down to, Bex, is evidence. There is a lot of evidence for the big bang. Not so much for the earth perching on a turtle's back. If you look in the abiogenesis thread you will also see that there is growing evidence for the possibility of life arising from organic chemicals. On the other hand, the evidence points against the earth being young, or all life on earth that's ever existed, arising concurrently.

When you say that there can be truth in myths, I agree. Comparative mythology is something I have an interest in. What some people dismiss as "myth," i.e. an untruth, I see as "greater truth." Metaphors can guide us to truths about life, and myths are meant to teach us.

However, that greater truth is lost when the myths are read as factual. In many cases, that was never their purpose.

In other cases, they might well document some real events that have happened to people. But we have to be careful about how we interpret them. They are not the same as historical documents. Even ancient historians such as Herodotus embellished their accounts to make them more fun to read. And when someone from an ancient civilisation says that the world was covered with water, we have to keep in mind that their concept of the world was probably very different, and much smaller, than ours.

If you want to try to make a plausible case for the earth literaly perching on the back of a turtle, you are of course welcome to do so.

I notice that CTD hasn't answered most of the questions I've posed here yet. I'm not holding my breath.
