Another point to add is that every christian that has complete faith (most) are practicing "doublethink" to believe 2 contradictory ideas at once. They believe that humans existed harmoniously at the same time as the dinosaurs? It is amazing how blind faith can be so insidious in cultures throughout the world. Why do christians believe in god? because they were told by people to believe in god. And the people before them. Christianity doesn't even make an effort to sound believable when you pick it apart.
