A couple of things. One, if people here are not willing to believe that the Bible is the Word of God, and completely accurate, than there's not much I can say to change their minds. The Bible is accurate, and is God's Word, that's the basis of all Christian belief. Christ himself referred to Adam and Eve as historical figures, very strong evidence supporting the original creation theory.
Finally, the Bible would not say it if it were not true. I depend on God to tell me the truth, so I depend on the Bible, for it makes the claim to be perfect, and everything that can check out, has, so I have no reason not to believe such a claim. However, man is flawed, naturally so, and I cannot take anyone's word as to what part of the Bible I can take literally and what I cannot.
