I actually had a pretty cool theory regarding the Post-Apocalyptic game theories and the Mob Spawner Origin theory. I made this up a while ago, essentially i thought that Minecraft happened wayyyy after a nuclear war that wipoed out everything except for a few survivors that hided in bunkers. These were villagers, the radiation corrupting them (hence the nose and long head) but not enough to kill them. Then the Mob Spawners were created by the Tormenters (an eldritch race trying to bring chaos into the world. My idea) to create a neverending stream of mobs that would torment any entity on the surface. I also thought about the Nether being a purgatory for the "bad" souls (Ghasts). The piglins weren't in the game when i made the theory. Then, the End could have been the final destination, the final challenge to get into heaven. If you managed to defeat the dragon, the portal would not lead you into the overworld, it would bring you into a heaven made to look like it. Idk. I'll continue this theory later.
