ELI5: If an electron can be two places at the same time, how do we know those are not two different electrons?

We know because when we do these types of experiments we can limit the number of electrons to one. If there is only one electron in the experiment but you can show that there is an electron in both places at the same time you know that it is the same electron. The theory is then that the same electron is in all its potential states (places) and can interact with things as if it were in those states as long as you do not observe it as it would then force the electron to be in one state.
