Ok then, but how, if the soul only gets recycled does the entire afterlife structure work? Dozens of heroes visit after lives of their respective religions. If those places don't exist dozens of tales (including Hercules, Medea and Rider) are false, especially Rider's.
@Kuro
if not for his origin he would have been swallowed by the dragon, that's why they changed it.
in the original Gilgamesh specifically became a target to make Satoshi a hero. He decided that Satoshi, like any person ought to have the right to choose his own destiny. And not to be led about by a bunch of conniving magi.
without this element to Gilgamesh he doesn't belong in the story period.
