Have you considered why the best explanations that the field of physics can offer are all interpretations? Maybe it's because there is a lot we don't know, and the patchwork of scientific theory we've built up iteratively over centuries is leaking in places for reasons we don't understand.

If you accept this, then it should be hard to mock someone who offers their own interpretation, since none of us know the answer to so many fundamental questions underpinning the physical universe in our cosmological plane of existence. At best, you knew more than he did about what we don't know.
