"The Graeco-Roman pantheon was a better fit with reality - a group of morally mediocre gods with their own agendas, mostly indifferent to what the mortals were up to."

It is a better fit in terms of The Problem of Evil, but it raises a different problem: What happened to them?

They seem to have been conquered by the other major religions and pretty much disappeared.

So the world's not really a good fit for them either.
