Miracles and Anti-supernaturalism

[Esquilax]

If something happens only in the "spiritual" World, it cannot be seen, heard, or known in the physical world.
If something from the "spiritual" wold interacts with the physical world, science can discover the disturbance or the effect on the physical world from this. Thus theoretically science should always be able discover the presence of "miracles."

Playing defense for a moment, the typical theistic response to this claim is that the being causing the miracle simply caused nature to behave in such a way that its will is done, so the effect, while actually miraculous, seems natural. To which the reply should be that anybody claiming that a seemingly natural occurrence has a supernatural cause while also admitting that this cause cannot be demonstrated, has no basis at all for saying so, and is acting irrationally.

Hopefully, my saying this will cut off any theists hoping to use it here, so we can all save time.
