Hi Jam,
"For the life of me I can't understand why intelligent people believe the stories in the bible. How can theologians who knows the bible and have read it several times still believe it to be 100% truth. What is it that I am missing."
As per the theory of evolution our brains are adapted not so much as truth detectors, but instead for our survival. Since humans survive in groups and are very social there is a great deal pressure to accept what the group believes as true. In this regard I find how science attempts to uncover objective truth very telling. For example, the very idea that hypothesis can be considered "scientific" only if there is some way it can be clearly proven wrong. Then the hypothesis only attains the elevated status of a theory only after rigorous attempts to kill the hypothesis have failed.
Thus it genuinely can be difficult to parse truth from complete nonsense when articulate adult leaders of a community insist the nonsense is real.
What I now find interesting about the Bible in addtion to the direct things you mention (the Adam and Eve story, the Jonan story, the Baalam story, etc), but a some of the more subtle patterns. One pattern in particular strikes me rather strongly, and that is the scope of the stories involving miracles changes over time. The story of Noah is world wide. The story of Moses involves all of Egypt. By the time of Jesus all the miracles shrink in scope and involve only a few people in the area directly around Jesus.
There is a simple and obvious reason for this -- to make unbelievable stories, beliavable, setting is important and a key is making the setting just out of reach. The bigger the story the more remote and distant the setting must be. Thus, Star Wars, opens with "A long time ago and in galaxy far far away..."
Cheers,
