how to set a background in unity

Hi, i’m really new to Unity and I want to make one of those basic and generic running games (as a test), and I want to have the earth in the background while I run instead of me just having a custom color. How do I set a background

Sorry if I post it in the wrong section, i’ve never been to the forums until now ;-;

Welcome!

If you are using UI you can just put an Image in behind everything.

If you are in 3D or 2D you can change the camera fill color.

Or you can put a quad up with a specific texture.

You could do it with a sprite if you like.

You could even do it with Green Eggs and Ham.

It all kinda depends on what everything else is doing in your game.

thanks!
