Not an axiom, just a prior with enough evidence to smash the probability of ghosts quite near to zero. You're welcome to pretend that I said "zero" and continue shadow-boxing a straw-man, but if you want to fight my actual argument you need to contend with "near to zero."
The difference between Woo of the Gaps and Science of the Gaps is that science is on the advance and woo is on the retreat, it has been this way for centuries, and the pace always seems to be determined exactly by the rate at which science advances rather than any actual opposition from the Woo camp. Nothing is over until it's over, but how much do you actually want to bet on a glorious turnaround? You do you, but for me the answer is "not much."
The rate of an army's advance through a particular town is 0 until they get there, but if you were to see the front lines moving towards you and put forward this argument as a reason to stay, you would be in for a rude surprise.
