The existance of a God is a point we could sit here and argue forever, just look at how huge this thread is, ultimatly it's trivial. It doesn't matter if there is a God or isn't because the necessity for one is there. Some people need something to believe in, they need to know there is something larger than themselves looking out for them, or else they may feel alone in this world. There are also people who don't need that, athiests. And that's fine. Everyone is just doing what they need to get through this life, if people need God, let them have it, if they don't, let them not.
