Many people believe that new scientific discoveries will always pose challenges for religion. However, recent cosmological discoveries which have been described as the fine-tuning of the universe apparently point to the possibility of a Cosmic Designer. It is because both the Big Bang and the basic structure of the universe seem to have been exquisitely fine-tuned to make the emergence of life possible. Even a small degree of change in these matters will make life impossible. In this paper, I will first introduce the various phenomena of the fine-tuning of the universe, e.g., the expansion rate of the Big Bang, the precise values of the constants of the basic physical laws, the nuclear resonance levels of elements like carbon. Then I will argue for the initial plausibility of the theistic interpretation of the fine-tuning, which, of course, is also facing a lot of challenges. Finally, I will respond to ten major criticisms of the argument from fine-tuning. I admit that there are still many complicated issues to discuss (e.g., multiverse) but I conclude that the contemporary discoveries of the fine-tuning indeed revive the design argument in the form of the argument from fine-tuning, and this argument should not be dismissed cavalierly.
