This is why I kind of admire the biblical myths; their selective details and smoky metaphors have proven incredibly resilient to new truths, and invite so much speculation.
The garden of eden could be in some far flung galaxy, from which we “life”, were expelled as microbes, thanks to the sins of relatives we wouldn’t recognize. The rib of Adam could symbolize the arbitrary evolution of sexual reproduction from asexual origins. The forbidden fruit could represent some inevitable nuclear holocaust spurred on by some intra-species conflict, which prompted life to be cast out and begin on another planet. Something unique about our shape of life means that we’re stuck in a cycle of destructive evolution that cannot be saved from itself, excepting for the divine intervention of some less imperfect shape of life.
Anyways, I’m rambling! I hope this sparks somebody’s theological-scifi bug and produces a mildly entertaining narrative in somebody else’s head. :)
