Correction. The Bible was penned by men at the inspiration of God. Countless men died to preserve it. God ensured that every "jot and tittle" was correct. And the wonderful God I believe in gave you the freedom to reject his love. How great is that?
The Bible even challenges mankind to PROVE its validity. That's fair isn't it? If it's from God, the thousands of prophecies contained in it will reveal that fact. If it's written simply by blind men such as you and I who "put their pants on one leg at a time" (although I don't think pants were the fad back then), then the predictions contained in the Bible most likely wouldn't have come true.
Start with the book of Daniel, which perfectly predicted the world government for several centuries to follow. Then look at the statistically impossible number of prophecies that spoke of Christ. There's plenty there to falsify, should you desire. It's truly remarkable.
