With all this discussion of dark matter and quantum mechanics, it may be useful to step back and discuss why arguments like these fail from the outset. They are merely arguments from ignorance.The argument from ignorance posits that any time science can’t provide a definitive answer to some question about the universe, one should immediately jump to the conclusion that the Christian God is the answer. It posits the Christian God as the default explanation for any and all unanswered questions. And, conveniently, any time a comprehensive theory covers some discrete issue on which no clear scientific consensus has emerged, the entire theory must be abandoned in favor of the “alternate” explanation that “God did it.” That is why the argument from ignorance is also occasionally referred to as “the God Default.”
The argument from ignorance is based upon a false dichotomy that things are either explained in their entirety by a comprehensive and consensus-based scientific theory or they are explained by God. It can be summarized as “If we don’t know with certainty how something happened, then God must have done it.” One might as well say that if something can’t be completely explained, it must be magic.
There is no justification for making the Christian God the default position. Any religion could claim the same in a game of “King of the Hill.” Where we don’t know something, agnosticism (“We just don’t know”) is the only rationally justified default position. We should only accept and believe a claim if it is supported by evidence. Until that happens, we should withhold judgment – not jump to the conclusion that the deity of one’s preference is the true cause.
The argument from ignorance also rests on the false assumption that what we know now is all we’ll ever know – that the “as yet unexplained” should be treated as “forever unexplainable” and that if no satisfying natural explanation is currently at hand, such an explanation is impossible. Accordingly, it posits, we are justified in throwing up our hands, ending our quest for knowledge, and simply concluding that God must be responsible. As such, it implicitly proposes an end to scientific inquiry in favor of blind acceptance of theological causation.
The best approach when confronted with a scientific question for which no clear scientific consensus has emerged is simply to acknowledge that we don’t know the answer yet. As history has demonstrated again and again, science will eventually plug the gaps in our knowledge. It is reasonable to wait for that to happen rather than inject an unnecessary and unjustified hypothesis (God) out of a desire for immediate certainty. The alternative to the God Default is, of course, the Naturalistic Default. That means that if we don’t know the answer to some scientific question, we should assume the question has an answer found within the natural world unless and until proven otherwise.
What, you may ask, justifies the Naturalistic Default over the God Default? Only that whenever a natural explanation to a scientific question has been assumed, that assumption has always turned out to be correct once more knowledge was obtained. By contrast, every time a supernatural explanation has been assumed for something ultimately explained, that assumption has been proven wrong. There are innumerable examples of the former, but no examples of a supernatural explanation proving to be correct. Ever. I think a 100% success rate is justification enough.
If science has taught us anything, it is that the unknown and the unknowable are different things and the first does not imply or require the second. Science has made a practice of identifying the unknown and explaining it. History is strewn with those claiming the unknowable, only to find the fact was merely unknown, and temporarily so that. As scholar Robert Price has said, “Experience tells us that whenever a scientist or historian has stopped short, shrugged, and said, ‘Well, I can’t explain it! I guess it must be a miracle!’ he has later regretted it. Someone else was not willing to give up, and, like a detective on a Cold Case Files show on TV, he or she did manage to find the neglected clue.”
Given that we have no experience with supernatural explanations, we would need to eliminate all natural explanations decisively before defaulting to a supernatural one. The burden then is always on the apologist to eliminate every possible naturalistic explanation before arguing for a supernatural one. In short, “We don’t know, therefore God” is not sound reasoning. “We don’t know” is never a good reason for believing any particular theory. All we can say within the bounds of reason is “We don’t know; therefore we don’t know.” In the meantime, however, we are justified by analogy in assuming the world works according to natural laws, and that a natural solution will be found if given enough time. The God of the gaps posited by the argument from ignorance is merely a pocket of scientific ignorance that is always diminishing.
The biggest problem with the argument from ignorance, however, is that, as used by apologists, God does not represent an alternative explanation at all. The purpose of an explanation is to dispel mystery. No valid explanation introduces an even more mysterious concept to explain the first. Assume you witnessed a man pull a rabbit out of an apparently empty hat, and asked him to explain how he accomplished this feat. You would not be satisfied if the man simply told you “it’s magic.” To say something is “magic” amounts to another way of saying we have no explanation. To identify the explanation of something as “God” without clearly defining God and the process by which God accomplishes the result in question is no different than saying the explanation is magic. It represents a glib and ultimately meaningless tautology.
To compare explanations, furthermore, they must be roughly equivalent. Scientific theories provide testable models that describe how things currently work and allow for predictions for how they will work under different conditions. Religious “explanations” do neither.How can they when God and his ways are considered forever unexplainable? These types of arguments can never justify nor legitimately advance belief in the Christian God.
