Wait, but peeling a banana is something that we come up with after a mental effort. So that definition doesn’t work like we want it to.

We all feel peeling a banana is not an invention—but how do we define it such that it is the case?

Invention is defined as something crafted by humans. What I’m saying is there seems to be a range/continuum of things crafted and a peeled banana seems to fit that definition. I’d like a better definition.
