  The standard arguments in favor of this position take one of two approaches: either they show that there is something inherent in the nature of the world that makes creation impossible or that there is something inherent in the nature of God that does. An example of the former is that change always proceeds from something to something else, as when a chicken springs from an egg or an acorn develops into a full grown oak tree. If this is true, it is impossible for something to come to be from nothing (ex nihilo). An example of the latter is that if God is perfect, it makes no sense to suppose that God could ever do anything new such as bring the world into being.
