I think we can safely say the myths are true because they've survived this long and still have something to teach us.

I've always admired the notion that for Jews, traditionally, the historical factuality of the scriptural stories was never important. That to me is a mature apprehension of their religious practice. You can find analogs in strains of Catholic and Protestant tradition, though they are not so evident. This is what is missing from the practice of fundamentalists and some evangelicals.
