The Atheological Argument from Geography

Occasionally, in the introductory philosophy courses I teach, a student will give an interesting argument for non-belief in God. Though I have never seen this argument in print, it seems familiar. Basically, the argument goes like this. Religious belief is largely determined by geography – where you are born and raised largely determines your religious beliefs. But believing something just because of where you are born and raised is not a reliable indication of whether that belief turns out to be true. So, in some sense, you are not justified in your religious beliefs. I will attempt a more rigorous reconstruction of this argument and offer an objection to it.
