Aristotle began his Metaphysics with the observation that people first began to philosophize out of wonder or marveling (thaumazein).
On those rare occasions that we late modern folks find an opportunity to contemplate things away from the noise, screens, and other distractions, we, too, might experience that same ineffable sense of wonder that motivated the ancient philosophers. We may find that the universe presents itself to us as a question. Even when we are confident about its answer (namely, God), the solution itself may raise other questions or puzzles.
Although questions of these sorts can be addressed in any theological discipline, the discipline of philosophy of religion is especially suited for such questions.
