All I can say is: Human created God, and by that, Human think God created Him... There will be no God if no humans will think about him.

Where does God lives or stays before he created the Heaven and the Earth? Does this God has a God who created him and the place he lives in?

And BTW, what is that light in what he say "Let there be light"? That is at the beginning before he made the sun and the moon and the stars. And he did not removed that light after he created everything.
