If thousands of years ago the Old or New Testament had descended slowly from the heavens as a blinding light, settling on the ground and revealing itself to be universally intelligible words (readable by all men of every language) printed on indestructible paper as yet unexplained and unreproduced by scientists, then I would be strongly inclined to believe its contents are the unerring truths and wisdom of God. That's not what happened, however. Instead the Old Testament was thought to have been composed over some thousand years, from the 12th century BC to the 2nd century BC, passed down for much of that time by word of mouth. Not surprisingly subtly and significantly different versions of many of the stories/books exist, and various churches have different opinions about which books are valid and can be included. Thus it's very hard for me to imagine the Old Testament is the inerrant and factual testament of God. The New Testament has a similarly complicated history, not having been begun until well after Jesus' death, and then composed of varying, evolving books coming into and out of favor for some 1500 years or so, until stabilizing somewhat in the 16th century. Again, hard for me to see an evolving text subject to the apparent whims of various ages being the inerrant and factual testament of God. I cannot understand, knowing what biblical scholars do about the creation and evolution of the bible, how anyone can believe the bible is literally true.
