Pre-Life? And Interpreting the Bible

Some random late-evening thoughts:

Religious people are so focused on the afterlife. What about the pre-life? As I understand it, there is no reincarnation in Judaism, Christianity or Islam. God breathes your soul into your mortal body at conception or birth, and then you live a mortal life and then live forever after with God and his buddies in heaven or suffer eternally in hell.

So, if there is no reincarnation (which oddly seems to be a popular theme in movies...hmmm), then you and your soul don't exist before your date of birth or conception. Past lives are also popular in movies, but I digress...or do I? I was going to state that people don't have a problem with not existing before their conception, but apparently some do.

Well, the point I was trying to make with logic is that if you have no problem believing you didn't exist before birth/conception, then why would you have trouble believing you don't exist after death? However clearly there is some popular fantasy that people's souls have lived mortal lives before and may yet again.

Clearly people are neither logical nor literal about their bibles.

And speaking of bibles, why is there so much effort at interpreting the bible and disagreements over it's interpretation? This god guy clearly had some issues with clear communication! You'd think the creator of all would be able to get his point across unambiguously.
