Creating a flat world in Minecraft is a great way to build large structures or experiment with different building techniques without having to worry about terrain generation. Flat worlds are also useful for creating custom maps or minigames.
To create a flat world, open the Minecraft launcher and click on the “New World” button. In the “World Type” drop-down menu, select “Superflat”. This will open up a new menu where you can customize the settings for your flat world.
