Something something... I can buy an afterlife, just don't buy there's a God, at least not one like any worshiped on earth, they all resemble kings too closely, and are too narcissistic. Enki might be the only exception, he was a scientist - stood up for man, gave us knowledge, but basically is as most scientists humble and could give a rats ass about being worshipped, considers us just the discovery channel. Keyword: Aloof.
Of course, that's just a myth. Still, my favorite mythological character. Anyhow, tangent aside my point - is no God, no need to worship. however if we're all each other, and we are the universe, or part of it and it's all different layers of conscious "agents" as Donald Hoffman calls it, then I think maybe a religion based on that could at least encourage fairness. One tenet : All are one, treat all as you would yourself regardless of race, nationality, religion, sexual orientation, etc.
Honestly, I see that as the penultimate human utopian ideal, but I think as long as we give elitism roots, we'll never get there, there's no room for elitism in a world where all are equal.
