So in minecraft there’s a theory about these ancient builders that built all the structures, see I have my own theory. So what if after the ancient builders made all the desert temples and jungle temples and shit, they didn’t just die after that, but they kept getting more and more advanced, like us, industrial revolution (why copper looks so industrial compared to everything else), cars made of copper instead of steel (do to how common copper is in minecraft and steel doesn’t exist), and skyscrapers made of concrete and copper. But the reason none of this is found in game is because after they died out (probably do to zombies taking over), do to not being maintained, skylines fell in on city blocks, cars buried, countrysides full of wheat get overgrown, highways crumble do to unstable tectonic action, and (if they got that far) satellites fell from orbit and radio/TV/cell towers fell. There are flaws with this theory but I’m working on it

Ps: also another reason the buildings aren’t found in game is do to the lack of quality do to cheap copper and plastic. I also believe that every update that adds stuff is steve discovering things so maybe he hasn’t found out about plastics
