Creation story as a metaphor makes sense in relation to evolution except I can’t explain significance of God forbidding the knowledge of good and evil. why would knowledge be represented as forbidden in this story of our origin? At some point we evolved beyond instinct and into knowledge, but why is that represented as “death” and not something the Creator would want us to grow into?
That’s a great question Lance, and to be honest, I’m not sure.
One of the things to keep in mind when evaluating Biblical metaphor is that there was a lot of “pop culture” involved.
By that, I mean that these metaphors were full of references to popular myths of the time, idioms, context-specific comparisons and interpretations, and all of the same things that we have in our stories today.
In other words, the symbolism isn’t going to always be perfect or directly applicable, and it will rarely be free of bias.
All that to say, there might not be any definite or applicable meaning there. But at some point, someone will probably tell you a meaning that makes sense to you and provides meaning to you, but it may have nothing to do with the actual meaning that was intended in that story 4,000 years ago.
