Evidence for Believing

[Anomalocaris]

No, a "supernatural cause" actually doesn't do anything by itself.    All it does in the hands of the person who asserted it is to let that person shout down the possibility of examining the so called "revealed truth" by more demonstrably reliable yardsticks to determine whether it is likely to be true or not.

The supernatural is an explanation for something that those demonstrably reliable yardsticks ascertain but cannot explain, not because it requires more observation and expansion of knowledge, but because it has no observable cause and cannot be known.

It does not open up any possibility whatsoever of getting closer to any sort of truth which could be verified by means less flawed than a person's fervent wish for something to be true.

It opens up the possibility of getting us closer to the sort of truth that we cannot empirically verify but is beneficial to our well-being and conforms with all human means of knowing objective reality.

How do you know, given an continuous history of ever expanding knowledge base explaining every more of the hitherto inexplicable, what can not be explained in principle can not be explained?

Any bullshit has a possibility, but only the most infinitesimal one,  of actually being closer to the truth than we could otherwise reach. .    Your "supernatural" is still indistinguishable both in its nature and in its effects from bullshit.   It has no more possibility of being true than any bullshit.      You merely combine egoism with idiocy so unselfconsciously that you could assert with a straight face bullshit that appeals to you is better than bullshit of other kind.
