The religion of my youth had a unique way of addressing this. Whereas most Christians insist that God is eternal and perfect, Mormonism teaches that God was once mortal like us, on some other world that came before ours. They suggest that God earned his supremacy by being righteous and faithful in his own lifetime. And that Mormon men can become gods over their own planets if they're good enough. Crazy, right?
It's just another glaring flaw in the whole Christian mythology. They're so quick to deny the possibility that the universe has simply always existed, yet they turn around and suggest that God has always existed. Otherwise God had to have been created at some point, and that creator had to have been created, ad nauseum.
