“The worldwide flood described in Genesis 6-9 is not historical, but rather a combination of at least two flood stories, both of which descended from earlier Mesopotamian flood narratives. Note that this does not mean all of the claims made in the Bible are false (or true for that matter); I am dealing here only with the biblical stories of the flood. (Also understand that the “slippery slope” claim of “all of the Bible is true or none of it is true” is simply an unnecessary rhetorical device designed to keep readers from doing precisely what scholars do every day: analyze each claim in the Bible on a case-by-case basis. It is not necessary to accept an “all or none” stance towards the Bible.)”
