Obi, you are right that it ultimately comes down to Faith.
I'm not sure how to address the many other points you've raised. Yes, we no longer look to Aristotle for certain scientific conclusions, but we do look to him for philosophic insights, for political ones, for insights on how to classify knowledge and think logically, etc. etc. His writings still have value, even if he didn't have a complete understanding of physics or other hard sciences. In the same way, we can look to Genesis for insight into human nature and human relationships, even if it is not (and was never meant to be) a clear picture of human ancestry.
And you continue to make the mistake that the Bible must all be taken literally, as if God dictated it verbatim. This is the mistake the Fundamentalists make, and it is the most common reason that Secularists have problems as well. I really recommend you look at Timothy Beal's "Rise and Fall of the Bible". It really helps to understand that the Bible is not a Magic 8 Ball that will somehow answer every question. It is a book meant to challenge us, a book meant for us to wrestle with. The Jewish tradition of Biblical commentary, of Midrash, is all about people interacting with the text, re-interpreting it, re-discovering it.
You are clearly a bibliophile. I think you can understand this approach to a great text. I think you are hung up on your perception (and it is one that is wrongly reinforced in our culture, by believers and non-believers alike) that the Bible is this inerrant guidebook, God's direct communication. It isn't like that.
So why do we give it credence? Whence it's authority?
