Page is an Evangelical Christian. In commenting on the debate between William Lane Craig and Sean Carroll in 2014, he states in a guest post on Carroll's website that: "...in view of all the evidence, including both the elegance of the laws of physics, the existence of orderly sentient experiences, and the historical evidence, I do believe that God exists and think the world is actually simpler if it contains God than it would have been without God." In the same post he criticises William Lane Craig's Kalam Cosmological Argument, saying that it "is highly dubious metaphysically, depending on contingent intuitions [i.e. the first premise] we have developed from living in a universe with relatively simple laws of physics and with a strong thermodynamic arrow of time."
