The false premise is that the religious explanation is the default or incumbent explanation, which must then be bettered or countered by "challenger" explanations such as science. It tries to frame the argument with religion as the "defending champion" for challengers to somehow unseat ("atheists need to explain how...").

In reality, of course, religious explanation has no such presumptive default or incumbent status. Religious explanations are just one of many potential explanations for how the world works and compete on equal terms with any other. And when the religious explanation really just boils down to some variant of "god did it", it becomes very obvious how inadequate that is compared to even the worst scientific attempts.

Related: religious apologists constantly try to pretend that criticisms or problems identified with scientific explanations somehow count as points in favor of their religious alternative. This is also a false idea. It is not a debate, where pointing out flaws in your opponent's argument helps yours "win". It is a search for truth, and finding fault with another theory does nothing at all to enhance your own.
