We aren’t special. Conciousness is a side effect of having so many neurons shaped by millions of years of social and environmental darwinism. We are actually barely concious to avoid confronting the fact that we are just walking meat.
If human head transplants were done, we would have proof that the soul is just a sophisticated algorithm held within our meat, but even then, our barely concious state will refuse to compute the actual implications.
Further our “singular conscious” is an illusion. People with various types of physical brain damage have had their awareness “split” and had something akin to two different consciouses in their brain. Even for “normal” people there are independent processes running in our brain. Our consciousness is in charge sort of the way the teacher is in charge of the nursey school. It might decide when recess is but it can’t stop that one kid from just singing for no reason.
Also to your point I think that if we could transplant a head we’d find that our sentience involves more than the brain. I think we underestimate how connected all of our systems are.
