If that's the case then I suppose they'd better include creation myths from other religions too. No doubt a small minority of adherents also believe the literal truth of these, though they are nowhere near as vocal as the Christians. Should we include the Great Green Arkleseizure from Hitchhiker's Guide too, or would that be pushing things a bit?

Creation myths are beautiful stories that say a lot about life and resonate with the psyche on a deep level, if you approach them with respect rather than derision. And like Pwcca said, religious moderates around the world (i.e. the vast majority of people) have no trouble getting truths out of these AND accepting the discoveries of science. It only becomes a problem when the myths are believed to be literal fact -- that's where you get a conflict with reality. People who believe these things word-for-word are missing a lot of the deeper meaning that the myths are meant to impart.

A lot of what I am saying was originally inspired, half a lifetime ago for me, by Joseph Campbell, and he in turn was inspired by Carl Jung. This would be obvious to anyone familiar with what he wrote and taught. The Hero With a Thousand Faces is considered one of his best, though The Power of Myth (a transcript of a conversation between Campbell and Bill Moyers) is very readable, and reading that was a turning point in my life.
