Who invented stairs?
What is the oldest known example of stairs in archaeology? Did they just use ramps before then?
Stairs and ladders were already in use by the time of proto-cities, so I'd guess they started outdoors as augmentations for difficult or significant trails

earlier than that. Foot delineation erosion on common paths.

That's almost a discovery, not an invention

They invent themselves. Walk up a solid slope a lot and your feet will carve steps.

The very concept of invention is specious. Read more history of science.
The concept.of stairs can be found in natural geological formations. It's technically a somewhat flat rock with another but higher somewhat flat rock next to it, making ascension possible.
We dind invent that, merely discovered it.
