Testing a Hypothesis about the Supernatural

[I_am_not_mafia]

How is the supernatural different from the natural if both can only be observed by how they affect the nature that we can sense?

The difference is in the CAUSE. There are natural causes and supernatural causes. Two categories of causes. Both result in effects in the natural world--otherwise we would not be aware of them. How do we distinguish? There are some effects that cannot be caused by naturalistic causes.

My italics. You are making an arbitrary distinction between a natural cause and a supernatural cause.

How is a supernatural cause different from a natural cause if both affect the nature that we can sense?

Need an example to discuss, here is one. 

Yeah, not even going to bother reading the rest.
