Why don't atheists believe in God? CHRISTIAN ANSWERS Good reasonable answer picked as best!?

Why would you ask christians why someone does not believe in god? When one reads the bible, it is plain to seed that a eternal creative god could not have done this. Any all eternal creative god could in no way have any favorite creations, no creation would be any better than the next. Could/would god be able to create anything it did not want to create. The bible god does that very thing on every page. The bible god seems like a childish emotional cripple when it creates things and knowing full and well how they are going to act, because god knows everything and wrote the book, and later down the road, god slays all these people for some ridicules reason, like having human sacrifices and then god has one of it,s own with a son. I say childish because it looks like god only creates so it has the pleasures to destroy the creation. The most amazing thing I read in the bible is about a god that created the universe and all living in six days and then takes three days to carve a few words in a rock. This is totally ridicules..
