Ah! Ok! I see where you are going with this.
So, materially speaking, everything is the same. I agree!
But... are they the same thing...formally? Meaning are the different neutrinos, electrons, neutrons, protons, whatever you want to call them, ordered the same way in everything?
they are all made of energy
that is the fundamental similarity that we can observe
different configurations of a fundamental substrate
now, if we hypothesise another layer more fundamental than that
maybe, "spirit" or whatever you want to call it
that we cannot observe scientifically
we can know for certain
that if this "spirit" can interact with observable energy
then energy and "spirit" must share some fundamental substrate
