I believe that there must be a God, the universe's existence strikes me as impossible without some outside help. It seems as good an explanation as any for our being here. As for worshipping him, been there, done that, and i'm not convinced. The thing that really put me off is the level of hypocrisy and beaurocracy within the church, so i figured it was more important to just try and be as nice a person as possible to as many people as possible, and trust that if there is a God and heaven etc etc, in his infinite wisdom he will understand what i'm trying to do.
