  Maimonides’ answer to the first argument (GP 2.17) is that given the world as we know it, change does proceed from one thing to something else. But why should we assume the creation of the world has to follow the same pattern? An account of creation is a theory of origin, how a thing comes to be initially. By contrast, an account of change is a theory of development or alteration, how one existing thing emerges into another. For all we know, the origin of a thing may be completely different from its development later on. Thus it is presumptuous to suppose that we can extrapolate from our experience of the world as it is at present to the moment of its creation. It follows that the first argument against creation is not decisive, which means that creation remains a possibility.
