https://en.wikipedia.org/wiki/Ancient_a ... hypothesis First, let's abuse this. :D Take events from religious texts and reinterpret them to have an extraterrestrial origin.
Heaven and Hell are instead a pair of binary planets. We assume these civilizations have existed for much longer than humanity has. Their technology is advanced, but modern (year 2560) technology has caught up to them so when they do "miracles" it's just existing technology that we know about. Like, turning water into wine? Pfft, it's just a chem synthesizer with a wine producing molecular configuration. Nothing special. Walking on water? Bitch, do you know what repulsorlifts are? You get the idea.
I propose that one planet is "Heaven" where both the main species are born. The "Hell" is actually a slightly smaller world in the binary planet system where the somewhat racist government of the "Heaven" planet sends dissidents. The "Hell" planet is inhabitable if not for mining colonies and biodomes.
Back in antiquity, these species stumbled on the human race and decided to abduct a couple of them to fuck with and put them in a biodome of their own on the "Heaven" planet. The subject Eve escaped the biodome and accessed another biodome where they were working on a GMO experiment with some alien fruit, and the bitch ate it, ruining the experiment. Pissed off, they deported both the male and female back to Earth and pretty much just dumped their asses in the desert.
Notable characters include Lucifer Morningstar, who these days runs a strip club on Virgo Prime. :P
