Actually, the evidence, via manuscripts (Dead Sea scrolls 250 B.C.- 135 A.D., etc.), and writings of early New Testament church fathers demonstrate that the Bible has been remarkably, and accurately, preserved down through history.
The Dead Sea scrolls (100,000 pieces), and other manuscripts, confirm the accuracy of today's Old Testament.
In totality, there are about 6000 manuscripts that support today's Bible.
The New Testament can be almost totally reconstructed via historical documents that prove the New Testament's accuracy.
Your statement just is supported by the evidence.
I meant to say:
Your statement is just not supported by the evidence.
At least from 250 BC, huh? Yet the OT supposedly goes back more than a millennia prior to this. As for the writings of early church fathers, we had a thread not long ago in which a church was found bearing inscriptions from "an early version of the Gospel of Luke." In the body of the story it mentioned that some of the verses have changed from that version to the one we have now. So much for "accurately preserved."
