[Minecraft] ...Who are the non-villager zombies?

Do I want to know?
gpt
The world of Minecraft is littered with ruins, shipwrecks, abandoned mineshafts and dungeons. The civilisation that built these structures disappeared long before the events of the game and the Minecraft protagonists, Steve and Alex, are the last surviving members of this advanced civilisation (let's refer to them as builders).

As for the non-villager zombies, they are zombified builders. Since the zombies can only survive in dark environments, it's possible that the builders accidentally triggered a zombie outbreak as they dug deeper into the Earth. The outbreak destroyed the builder's civilisation and any survivors (other than Steve and Alex) fled into the end, where they built the end cities before turning into the Endermen.
