What is created in our world is accessible by science i.e. its influences are obvious in the world, so it's not needed to consider spiritual, and intangible effects as results of existence of some incidents, and then try to complicated justification; however, it doesn't mean that there are no metaphysics creatures, but the debate is that what is happening in the world can't be studied, and is not be measurable, and searchable although its cause is hidden (that would be nonphysical, because the cause is different from the effect); but physical effects of that thing are tangible and can be studied, or will be studied by new technologies in future to discover their new aspects such as those matters that are called immaterial ( and they don't have effect of the present substances) and it would be considered as superstition if we thought about them some years ago
