" I view Genesis chapter one as a simplified parable, not a scientific document." Fine, but once you start down the route of " Oh, that bit is a metaphor, or a parable" or whatever, where do you stop ?
Adam and Eve, a parable ? Well, yes, it is, sort of in actuality, but for Bible believers that means that original Sin did not happen, or " The Fall", only in a Parable, so sin did not enter the World then at that time. ( So Paul got it wrong).
And so on. Many other questions of faith arise if it is all metaphors and Parables.
The easiest conclusion to come to is that the Bible is a collection of writings made over several Centuries, by mere men, and is not the Word of God.
If you come to that conclusion, why believe in the Bible god as a Creator ?
