Keating contends that both explanations face a problem. According to Keating, "from a purely scientific point of view, the faithful have a big problem: They can offer no indisputable proof for this belief [in God]." On the other hand, advocates of the multiverse, like the late Stephen Hawking, "endorse [the notion of a multiverse] knowing there’s not a single shred of hard scientific evidence that supports it. And how can there be? There’s no way we can access another universe." Keating concludes that both religious believers and those who believe in the multiverse are forced to take a leap of faith; the only difference is that "those who believe God created the universe are intellectually honest enough to admit that they do so on the basis of faith," while multiverse advocates are not so honest. He ends the video with a question: "Who’s taking the bigger leap?"
I would say that the answer to this question is quite clear--it is the believers in a multiverse who are taking a bigger leap. Yes, neither religious believers nor multiverse believers have "indisputable proof" for their beliefs. However, I would contend there is plausible (though not indisputable) evidence for the existence of God, such as our belief that absolute standards of right and wrong exist, and the existence of human consciousness. In contrast, these phenomena (and others) are difficult to explain within the evolutionary framework implied by the multiverse hypothesis. In short, the "leap of faith" involved in believing in God is, I would argue, a much more reasonable leap to make than that involved in believing in a multiverse.
