Bobby Conway: We’ve been talking about some of the different arguments for the existence of God. What is the argument from fine-tuning?

Dr. Craig: The argument from fine-tuning is a version of the argument for design that appeals not to biological examples of design, but to the initial conditions of the universe that are put in at the beginning of the universe in the Big Bang itself. And this argument can be simply summarized in three steps. Premise one: the fine-tuning of the universe for intelligent life is due to either physical necessity, chance, or design. Premise two is: it is not due to physical necessity or chance, and here you would present arguments to disqualify those two alternatives. Three: therefore, it is due to design. So, this argument, if successful, gives us a cosmic designer of the laws of nature and of the universe.
