That's not a good analogy. We are not postulating the existence of imaginary entities.
The fact is that things exist and they either have awareness or they don't. Materialists assume that things don't have awarenss unless it's proved that they do. But why make that assumption? Simply throwing arms in the air shouting "ridiculous" and "teapot" and "Thetans" is not an argument.
The only "thing" we have experience of being is ourselves. And we know that we are aware. So we know that at least some things are aware. We don't know for certain that there are things that exist that at unaware.
We have direct proof that a thing can be aware. (Ourselves)
We have no direct proof that a thing can be unaware.
Simply making the assertion that most things are unaware, and any other view is ridiculous, is not an argument.
