MillyR, maybe I got the wrong end of the stick but you said "there are certain topics that science can't really comment on" and "I would say that the immortal soul is supernatural, and the supernatural cannot be studied through science."
...reading again I see that you say that the soul can be studied rationally but not scientifically. I am not sure I understand the distinction. At its most basic science means looking at the evidence and making sense of it. Any philosophy which isn't rooted in evidence at the points where it intersects with the physical world is built on shaky foundations.
For this reason, cartesian duality (the idea that the mind and the body are made of two quite different kinds of stuff) is no longer taken seriously as a working hypothesis in modern philosophy or science as far as I know.
Jinglebelly cites a couple of popular books, but this doesn't support the case existence of the soul is a seen as a live option in serious science. There are no researchers on autism, cancer, infertility etc...saying 'we have made a breakthough by understanding the role of the soul in this condition'
I make no distinction between invisible leprechauns and immortal souls. Neither are detectable, and there is no evidence that either exists. Sure there are plenty of real invisible things - magnetism, gravity, oxygen, electrons...but they are detectable.
Pointy things - I would say that the working hypothesis on the immortal soul is exactly the same as the working hypothesis on invisible leprechauns. There is no evidence that either exist. Hypotheseses are proposed explanations for observable phenonmenon. There is no observable phenomenon in either case, so no need for a working hypothesis.
Getting back to the point about evolution and religion, it was that biology (not just evolution, but development, neurology etc... ) provide a coherent explanation of life without recourse to supernatural (and unknowable) explanations. Lots still to discover, but no soul-shaped-hole in the evidence.
So people can and do say they believe in evolution and in Christianity, but they are ignore the fact that biology comes to some strikingly different conclusions about how human beings work than the religious viewpoint offers.
People skate over this and concentrate on the creation in 6 days thing - as if reading 'days' as 'few million years' solves the problem of reconciling the two explanations of the origins of life.
