Perhaps there were moments in humanity's social evolutionary history when religion served a progressive purpose, in the sense that it allowed humans to make that transition to begin asking questions of how they got here, how our world came to be and so forth.

This was to serve as the prelude to the concept of scientific inquiry of our existence and how our world came to be.
