Which is an interesting argument because: do neurons somehow create a soul (as you mentioned), or are do neurons somehow attract souls, or do souls choose what to inhabit. In the first case it posits that a “soul” is purely a function of biology. In the others that there’s some sort of inextricable link between the two (which in the absence of any theory of soul or how these are linked to biology, seems rather far fetched, unless of course souls could choose to inhabit anything with sufficient degrees of freedom: a brain, a mega computer, a planet, a galaxy)
