Here we see @ standing on the ground.

This is what you walk on most of the time. A simple white dot on a dark background. You can't miss it. It is the ground. There isn't much special about the ground. It is below you. It is slightly further away if you are levitating, but not much.

There are only a few situations where the ground won't be there for you. The obvious one is if you step into a chasm but if you like surprises why not try a potion of descent or running into a pit bloat?

Honestly, if you're getting sick of the ground at the depth you are on you should just stick with staircases. It's much safer.
