gumby,
You are correct. The fact is, I cannot offer proof that the original texts were not altered. However, it is not mine to offer proof. We (as in renowned historians as well as the average Joe) accept plenty of ancient documents as historically accurate with no corroborating evidence to back them. The "burden of proof" is not on those accepting the texts as accurate. The burden is on those who would claim it to be inaccurate. Otherwise we would have very little evidence of anything in ancient history. Now, if you ask whether or not I believe the bible deserves scrutiny, I would answer yes. Further, I cannot say that the bible is the exact representation of the original texts. The point is that it's no less historically accurate.
rem,
I don't believe the "special pleading logical fallacy" applies to me in this case. In my opinion, quite the opposite is true. I believe the bible deserves the same credit as any other ancient document that we, as a civilization, accept as accurate. As I said in the preceding paragraph, I believe the bible should be scrutinized. Yet, it should not be immediately discounted as a "fairy tale" simply because the earliest documents date back to within one generation of when Christ walked the earth. This is certainly much closer of a time from original writing to existing copies than is the case with many other documents held as accurate.
