Question: What would it look like to be living on an electron, whizzing around a proton, inside a molecule, inside a living being?

Depends on what _you_ are made of. If you're small enough to live on what is a point particle in our universe, then your concept of "looks like" will be different than ours. For one thing, your interaction with photons will be different than ours.
