“For if, as they say, everything has had its beginning of itself, and independently of purpose, it would follow that everything had come into mere being, so as to be alike and not distinct. For it would follow in virtue of the unity of body that everything must be sun or moon, and in the case of men it would follow that the whole must be hand, or eye, or foot. But as it is this is not so. On the contrary, we see a distinction of sun, moon, and earth; and again, in the case of human bodies, of foot, hand, and head. Now, such separate arrangement as this tells us not of their having come into being of themselves, but shows that a cause preceded them; from which cause it is possible to apprehend God also as the Maker and Orderer of all.”
The complexity and diversity and interdependence of things in the creation argues for the Creator being their source.
