Yes, it is a shaky argument from silence, James. We don't have a complete
inventory of the conceptual framework and content of traditions from ancient
times, so while we today may not know about someone, does not mean that the
ancients did not know about someone, or that they did not make said someone
up at some point. You just cannot confirm either way.
