Take for instance Dr Garret's first comparison between Plato and Homer on whether the Gods were born.
Plato assumes that the Gods are eternal but Homer as does Hesiod has the Gods as being born. Is this actually a contradiction? Mythology operates outside of our commonplace understanding of space and time, so to me the two views don't have to be presented as a contradiction. The birth of Zeus from Rhea, for instance, is in a sense always happening, because it's an eternal reality.
Even if the birth of Zeus is eternally happening, so is the state before Zeus on born and the state after Zeus was born. If the Gods are eternal as Plato believes, there there could be no state before any of the Gods were born to talk about in mythology. Translation, both beliefs probably cannot be literally correct. They might both be correct ways of understanding the Gods in that they each tell you something important about the Gods
