Minecraft pretty much explained the universe. What's a Minecraft map before it starts rendering? Nothing. Yet it can begin existing in seconds. What is a Minecraft map expanding into? Nothing. Yet there is endless space for it to expand into. Who created the Minecraft map? An algorithm, triggered by any random idiot. What is the purpose of the Minecraft map? Whatever you want to use it for, within its physical laws. Does the map understand what created it? No, it doesn't need to.
