Abstract
It is most improbable a priori that laws of nature should have a form, and their constants have values, and the variables of the boundary conditions of our universe should have values, of such a kind as to lead to the evolution of human bodies. If there is a God it is quite probable that there would be human bodies. Our only grounds for believing that there are other universes, are grounds for believing that those universes are governed by the same laws and have the same boundary conditions as our own. Hence, the existence of our universe is evidence for the existence of God
