Cant Add Rigid Bodies

So I am making a simple 2d platformer. This is my first game so I’m following a tutorial. I have some knowledge with unity as I have messed around with it before. So in the tutorial I have to add a “RigidBody2d” but when I search for it it doesn’t come up. It only comes up with “new script”.

You should have this option.

If not, reinstall Unity following a tutorial to see what packages you need to add.

Bye.
