How are ancient myths to be understood in light of Scripture, and vice versa? The article, “Is Genesis 1–11 a Derivation from Ancient Myths? – Answers in Genesis,” helps give an answer.
The question is not only, “which came first?”, but more importantly, “which is true?” Some would , I suppose, try to redact the various ancient myths with the Bible in order to try to get at the “original” account, but doing so only denies the possibility of the full veracity of any of the accounts.
But as Steve Ham writes, the Bible is either all true or all false. If the Bible is only part true, then which part is God’s Word and which is not. Rather than try to interject and interpose our opinions and thoughts on what the Bible means, or how we are to “take it,” first ask the question, “What does it say?” What does the Bible say, and what does the Bible say of itself?
