The laws of nature are not postulations.
When I say “impossible,” I define it as that which violates the laws of physics. If anything could violate them they wouldn’t be laws. It is not unfair or irrational to presume that the universe follows the laws of physics when trying to make empirical inferences. Remember, we are talking about a particular method, here, not about what is absolutely, hypothetically possible.
In other threads I’ve used the analogy of criminal forensics. If we find a supect’s fingerprints at the scen of a crime, should we assume that person left them there or should we consider supernatural explanations for how they might have gotten there? In order to practice science you must make certain assumptions or become paralyzed by the inability to rule anything out.
Once again, I am not talking about absolute ontology or epistemology, I’m only talking about what is required in order to apply scientific methods of discovery.
