Your point is interesting, but what makes you think that the sun would easily exist without any god? Big bang?
An explosion that nobody triggered and after which all the stars and planets would appear at their exact place? I would believe it when science will prove that (which will never happen since science itself is recognising that a superior being might be at the origin of the creation of the world).
