I define a "thing" as anything observable; it's what most people mean when
they say something like "concrete reality".

Quantum Mechanics can be formulated in a way that makes no use of wave
functions whatsoever, in fact that was the way  Heisenberg originally did
it. It was only 6 months later that Schrodinger came up with his wave
equation. Both methods come up with the exact same probability prediction
and which method used in the calculation is entirely a matter of personal
taste. And there is no arguing in matters of taste.

Your point was "everything is a wavefunction" and your point was about as
far from the truth as it's possible to get.
