The wavefunction is just a mathematical tool that allows calculation of expectation values of these observables. Any other interpretation of the wavefunction is just pure speculation, unsupported by any evidence.
OK not quite "unsupported by any evidence" but yes the various interpretations of what the waves actually are still in debate.
