Another problem that each of the world religions must solve is that none of them teach a way of life that works in today's (urban) jungle.
Today, all of the major world religions come down to us through millenia of empire. Viewed as myths, these stories, for millennia, have not been shaped by any evolutionary process of the kind described in the "villages in a jungle" analysis on IDEAFARM.COM. They are not stories that put the universe in human terms to teach a "way of life" (roles and rules) for small groups of about 50 persons, villages in a jungle.
