Why should I believe in God?

I'm not here to insult those who believe in religious dietys and god's, but tell me why. Why should I believe in him. Don't give some stupid sob story about how 'he saved my life!'. I don't want to here any bible fairytales either. Is there anyway you can prove this to me? I doubt it. I've yet to hear anything that makes sense. I would sooner go to Buddism (sp?) or Laveyan Satanism before Christianity or Catholicism. So why should I believe. Instead of confusing me with conformity and organized religion, tell me why I should believe.
