*rolls in two cents*
God is a intresting topic.
I belive the current or modern beliefs in god are human constructs. It comes from human's need for purpose and the human desire for of immortality as well as the desire to inflect a amount of control.
What I mean by this, before god consepts were implimented there was not a culturial moral set. It makes for a brutal society<killing, maiming, stealing, etc.>, a god makes one even need to second guess when thier alone, a absolute rule set. It also gives a level of hope, something after death and some greater reason for existing. When humans create something it normaly has a purpose, the theorical reasoning is all things must have been created for a reason as well. To bring a sence of vanity into it many of the religions put a human like leader as the "god" and or "gods". On top of this organized religions, introduces a class system having thouse that are of greater "holy" stature.
Now if by some chance this world was created, what would ever make anyone belive they could find any proof of a creators existance. For all we know our universe as we know it could be a minor subatomic impurity, since all things are relitive.
My belief comes down to, there may be a creator of the world, a god as it may be. I don't belive he has any intrest in me nor the human world. I also belive in manifest destiny <we make our own path> with internal subconscious karma <our own internal morals, memories, instinct, and personalities root make up a personal version of the reward/retrobution>.
