Even if our modern Bible conveys 100% accurately the original crazy crap people wrote down thousands of years ago, it's still crazy crap people wrote down thousands of years ago!
Then, I suppose, a Mark Twain novel can have no truth to it. The original authors wrote in stories to convey truths of humanity. Much of the Bible was written as a myth. For example, Genesis chapters 1-11. The original authors probably wrote it sometime between 1020 and 930 BC. They knew full well that it did not contain the exact details of creation. That was not the author's intent. Rather, the authors were attempting to show human life as it should be, and humanity's vanity. The folly of our pride and the source of our unhappiness: sin. They did not attempt to convey an exact history-- anyone who tells you that is plain wrong. They looked around their world and saw so much hate and evil, and their goal was to explain it. The truth of the Bible is not in its precise figures or its exact locations, but rather in its treatment of the human person.
It seems, however, with your worldview, there can be no such thing as truth because you have reduced us to mechanistic beings. In your materialistic thought, there can be not truth, because we can't even know anything: everything is an illusion.
We need to return to a study of the natural world around us that we can once again understand ourselves as people and not as machines.
