There are only two obvious point to be made about any mythology. The first is that myths aren't about real phenomenon but about imaginary projections. The second, and more interesting point, is that myths reflect the anxieties and aspirations of a moment in time that is then locked into a kind of literary amber. Plato wrote The Republic during a time of great instability, in an attempt to lock down his preferred notions of social order. Christian mythology arose during the late Axial period when earlier myths were falling apart and people were looking for simple stories that could provide some sort of guidance during significant change (e.g. the slow collapse of Rome and the rise of feudalism). All myths are freeze-frame impressions of huge social stress, which is what makes them intellectually interesting. But if we make the mistake of imagining them to have any other bearing on reality we've missed the point entirely.
