On the subject of the nature of the gods, the first question is Do the gods exist or do the not? It is difficult you may say to deny that they exist. I would agree if we were arguing the matter in a public assembly, but in a private discussion of this kind, it is perfectly easy to do so.
Where did God come from? If we decide this is an unanswerable question why not save a step and conclude that the origin of the universe is an unanswerable question.
A man has no religion who has not slowly and painfully gathered one together, adding to it, shaping it; and one's religion is never complete and final, it seems, but must always be undergoing modification.
