Viv, I used "computation" in the context of human thought. It was you who applied it to computers.
Anyway, claims of a soul treat it as a thing. Unless you've something or some reason to show it should be treated differently, your trolling is of no value.
If a soul is a thing, it does not need to be a physical thing, in order to be a thing. You are presupposing reductionist materialism, and therefore begging the question. (Yeah, yeah, you will say I'm wrong, I don't know what begging the question is, and I'm dishonest. There I'll save you the bother. Predictably what you won't do is supply any argument or evidence for any assertion you make)
Frankly I am doubtful about "souls", but dismissing them on the grounds that they are not material is stupid, because they are not claimed to be material.
Non-physical things do exist, such as numbers and thoughts. The question is not whether non-material things can exist, the question is whether a "soul" is among them or not.
