If the condition in our universe were not what they are, within a very small margin of flexibility, no life of any kind would be found in this universe. Thus, while the present universe is a fit habitat for human and other life form of life, the initial probability of there being such a universe is quite small. The confluence of so-called "cosmic constants" is improbable enough on the assumption that the universe is uncaused and undesigned; it is even more improbable on the supposition that we owe our existence to Creator who has it in for us. If, on the other hand, our lives are special, and if what makes our lives special has anything to do with the physical condition in which we come to have our lives, then the good of human life depends upon the Creator as well. This is cause for considerable comfort, for it offers an important clue concerning the Creator’s good intentions for humans. Our bodies locate us in a physical world of astonishing complexity, apparently ordered by its Creator to the goal our physical well-being.
