“We should not read Genesis 1-2 without asking the question, “What sort of creation account is this?” That is because we should not expect that every culture would be interested in the same sort of creation account. Their values and interests may lead them to choose a different story than our modern culture might choose.”
Genesis was written by and for early Hebrews, not Greeks or western scholars. It was written by very literal-minded people who thought in concrete terms, not abstractions. And Genesis is partly an ‘identity’ story, as he said, but it isn’t just about man’s identity. It’s also about God’s introduction to man.
