What philosophical evidence is there against believing in non-physical entities?

[Arkilogue]

And to kinda sum up what others are saying....the question is phrased wrong.
The real question is, "What evidence is there for believing in non-physical entities?"

So far, the answer seems to be....none.

I'd have to say if there WERE evidence, then pretty much by definition, the thing would have to be partly physical.  So if there were a God, and he somehow influences the Universe, then that part of God which allows for influence (i.e. the application of force, or the creation of material) would have to be said to be physical.

We know of 5 other types of quarks that can make atomic nuclei....and we are made of the lightest type.

If there are other entities/realms that are parallel/overlaping our realm....4 of them would be more "physical"...more dense...not less.
