From the perspective of a biblical worldview, the Flood is the most catastrophic event in the history of humanity. From the perspective of Internet spoofers, it is also the most comical. But is it really silly?
First, common sense demands that we allow for both natural and supernatural explanations to make sense of the universe in which we live. Realities such as the origin of life and the phenomenon of the human mind pose intractable difficulties for merely natural explanations.
Furthermore, reason forces us to look beyond the natural world to a supernatural Designer who not only sustains the world but supernaturally intervenes in the affairs of his created handiwork—which is precisely what the Genesis Flood account entails.
Finally, if we are willing to believe that God created the heavens and the earth—as opposed to the untenable notion that nothing created everything, that life came from nonlife, and that nonlife gave rise to objective morals—we will have little difficulty believing the Genesis account of Noah and the Flood.
