@Narkissos: Thanks for your discussion about "inspiration." When I say "inspired," I mean it in the way that I was taught by the Witnesses--i.e., that the Bible is the infallible, 100% true, unalterable word of God. I was taught that there were no scientific inaccuracies or contradictions in the Bible, and that this was evidence of its "inspired" nature. If the Bible is God's word, and God cannot lie, then God's word cannot contain any lies.
You can take that syllogism and apply it to the flood: If the global flood of Noah's day didn't happen, but the Bible says it did, then the Bible contains a lie and can't be God's word.
Of course, this is based on my viewpoint based on being raised to believe in a fundamentalist interpretation of the Bible by the Witnesses. I recognize that there are more liberal schools of thought that rationalize some of the more embarrassing, outdated, and unscientific parts of the Bible. To me, a more reasonable response to these issues is to recognize that it is likely that no "God" had anything to do with the Bible and it's simply the work of men.
