While I respect believers of the bible or other ancient holy books, what you just brought up is why "truth" is so elusive and why any group claiming a monopoly on it must be viewed with caution....
Whatever our beliefs on various spiritual matters, we have to admit first of all of where they originate. If they come from the bible, then we start by saying that these anceint scrolls in ancient tounges are not what they were when first written, and there is no way to verify the truthfullness of their claims... You can believe the claims, no problem, that is everyone's right. But all we have left are these old, translated scrolls. What bearing should that have on belief? I think it should at least be acknowledged by believers, because it affects me.... How do you overcome that arguement?
There is one other thing, people love to argue, and they love their opinions... Intellectual honesty is something that is missing in many debates, and often debates involving the bible cannot be intellectually honest because it is so open to a wide variety of interpretations....
