Why? Because you say so?
You are setting up an impossible premise here. True, there ARE biblical inerrantists out there who are very strict 24/7 creationists, but...and I do hate to break this to you...they comprise a minority of Christians. There are quite a few of us who understand that while the bible, in its original state (the originals of the writings of the prophets included in it) are probably pretty accurate as far as the understanding of those writers went, MEN have been involved in translating and transcribing it for several thousand years, if one counts the OT as well as the NT.
...........and y'know what? We don't HAVE the original documents. For you to insist that we have to take the bible utterly literally, with 'no room for riddles or interpretations' is insisting that we adhere to a standard we don't use. Only you are insisting that we do it.
Shoot, even the "KJV only" biblical inerrantists understand that different people can interpret a verse in different ways.
As to science....the Bible was never supposed to be a science text....and as it turns out, most Christians understand THAT, as well.
