Funny that you should doubt the historicity of the Bible.
Did you know that the New Testament is the single most attested work of ancient literature in existence?
There were no photocopy machines in ancient times – no printing presses. Every copy of the Bible had to be written out by hand. One would think that after thousands of years and hundreds of generations of hand written manuscripts, that the content of the Bible would surely have become skewed. After all, it's hard enough to pass a simple sentence around a room of friends and have it return to the originator unaltered.
Yet the evidence shows that this is precisely what happened with the New Testament. The Apostle John finished off the book of Revelation around 95AD, closing the biblical canon. We have more than 24,000 ancient manuscripts of the New Testament, some 5000 of them written in the original Greek and dating from 125AD to no later than 1520AD. What do you think happens when we compare the very oldest manuscripts to the very latest?
We find no change in substantive content...PERIOD! Sure, the odd word here or there got smudged, or the odd line was accidentally repeated, or the odd margin note improperly included, etc. But through the science of textual criticism, we are able to figure out how the original should have looked. Incidentally, none of these transmission boo boos does anything to alter the meaning of the text. Thus the evidence clearly supports the historicity of the New Testament. And the New Testament clearly affirms the authenticity of the Old Testament. Yes, the Bible is primarily a religious book. But additionally...YES, it most certainly DOES report accurate history. To suggest otherwise is to ignore the vast body of supporting evidence.
