Before we stop, if you don't mind, could you answer why you are dissatisfied with the idea that there's a soul, and why we need to do away with it 100%?
To be clear, I really do take issue with the 100% aspect. There are many psychological functions that are clearly at least mediated if not outright caused by the brain and body.
But I think some people say "there's so many functions that are physical, that probably 100% are and we just don't know it yet." But that doesn't seem logically any more forced than "there's a soul that's mediated by the brain," so I don't know why people are so willing to give up the soul.
