i suppose you get into this later but with all the radiation that is part of how the weather goes so crazy and the earth's crust slips into a new orientation, a lot of mutation also occurs, not just because of the slim populations of survivors but their genes get jumbled as well
what i was more interested in when i asked about the Judgement Day stuff was more about how there was this notion that there would be an intervention, all eyes would see him all that stuff... and the trial of every individual to see the nature of their souls? like the egyptian stuff about Maat and the weighing of the hearts
i guess what i'm trying to say is
as survivors of this cataclysm
are we back to stone age tech, depending entirely on our memory of science, to rebuild the world, like, i know i could probably guide the process of recovering at least a dozen different industrial processes, i'm not sure... metallurgy, fermentation, mycology, concrete... furnaces, charcoal, purifying water, electricity, which would require finding and refining copper and silver
are we really back to square one or did someone ever manage to get off planet because the stuff about "ascending to the heavens" re enoch and jesus kinda claim that humans did manage to get off planet which means that they could come back and help the recovery process, new heaven and new earth, etc
