The problem with using the bible as "proof" of God’s existence and nature, is that even if all the events within its pages actually occurred, it could still not prove God for the simple reason this video points out: God might not be the God you think He is, or even the God He thinks He is. The most likely scenario, however, is that He is a construct of the people.
Man created God in his image.
