"Questions atheists can't answer" is a dumb argument

One of the most common forms of Christian argumentation, which you can find tons and tons of examples on websites and video sharing platforms, uses the form "X questions atheists can't answer".

For some reason many Christians and Christian apologists believe that not only is this a completely legit form of argumentation but that it is, in fact, some of the strongest proofs of God's existence (and, obviously, that it's the God of Christianity described in the Bible.)

Yet, it's one of the dumbest forms of argumentation. That's because it's a direct textbook example of straightforward argumentum ad ignorantiam, ie. argument from ignorance.

("Ignorance" in the name of the fallacy does not refer to the person making the argument being ignorant. It refers to "not knowing (something)". In other words, it's an argument of the form "if you don't know (this thing), then my claims are true.")

It doesn't even matter if those questions can actually be answered or not. Even putting aside that question, even assuming that those question legitimately cannot be answered, that "atheists" indeed "can't answer" those questions, that means absolutely nothing.

Your position doesn't somehow become valid because someone doesn't know the answer to some question. It doesn't even matter what the question is.

As an example, even if someone can't answer the question "where did the Universe come from?" that doesn't somehow make the assertion of "God did it" any more legit. It merely means that that person doesn't know the answer to that question.

The idea behind the argument is genuinely strange. It's like an answer, any answer, somehow becomes valid if others can't give an alternative answer. "If you can't give me an answer of your own, then my answer is correct." That's, rather obviously, not how it works, at any level.

There are still open questions in science, that's certain. However, the correct approach to studying those questions and trying to find out their answers is not to just jump to a completely asinine "God must have done it!" Even if some questions genuinely have no answer, that doesn't somehow justify religious beliefs. It simply means that we don't know.

(By the way, this is something that too few skeptics point out when presented these "questions they can't answer". They fall into the trap of trying to answer those questions. The problem with doing that is that it inadvertently legitimates the underlying argument, in other words, that if the skeptic indeed can't answer the questions then it somehow gives credibility to the God claim. Skeptics shouldn't start answering any questions without first making it clear that it doesn't matter if they can answer them or not. It's not a valid form of argumentation. It's an argumentative fallacy.)
