And we aren't made of anything other than what all the animals are made of, and the underlying processes in our brains aren't physically unique. And there's no "spirit" or "soul" needed to explain anything.
The word spirit comes from Latin spiritus "breath." Ditto for the term for soul "psyche" which comes from the ancient Greek psykhe with the original meaning "breath." That's all that "leaves us" when we die (as we "have our last breath") and from where all the magical thinking came.
The consciousness is just a product of evolution, and "a kind of self awareness" exists by animals too. Not much different from what we observe by ourselves, and actually of direct evolutionary advantage.
