"god" isn't any more the "null hypothesis" for anything then undetactable pink graviton pixies are the null hypothesis for gravity.
To you, maybe not. Your belief set regarding origins, however is ignorant of what nature existed in the past so is not equipped to deal in the issues. So you either keep ignorance as your default, or look for something above the paygrade of science that does cover the issues.
Neither of which apply to the basis used in origin sciences, of assuming nature was the same. No tests exists for that, nor can the belief be falsified by science.
Falsifiability and testability is requirement number one for any scientific hypothesis.
