Olga:
Okay.
All the evidence suggests that consciousness is a function of the brain. Damage the brain in particular ways and the consciousness goes away or is changed in other ways.
I am not aware of any good evidence that shows that a person's consciousness can exist independently of their body, including after death.
The brain, when it is traumatised, can do all kinds of strange things. There are many reports of "out of body experiences" (including many "near death" experiences), but there has never been good evidence that people actually go out of their bodies. For instance, nobody ever sees something they could not have seen from inside their body. People report such things, but there is never good independent confirmation.
What makes you think we have a soul?
When I want to move my arm, is there a message that goes from my soul into my body and then somehow gets transformed into the nerve impulses that cause the muscles in my arm to contract? If so, then how does that transformation process work? How does the soul cause the necessary electrical impulses to be produced? And how can we tell that it's the soul that is the root cause, rather than just the brain? Note: we can observe the brain firing off nerve impulses, using real-time medical imaging. We can't image the soul, however.
It is well understood that certain functions of our brains are automatic and unconscious. We don't have to think about breathing all the time, or about causing the heart to pump blood. But other areas of the brain have been found to fire off nerve impulses as a result of conscious intentions and such.
Do you think it is possible that the soul doesn't exist?
