What interests me most about people who believe in an after life, is that most of them believe that the brain has some control over our functions. Tell them that a person can no longer talk, read, write, reason properly, or remember things due to a brain injury (i.e the damage to/death of part of the brain) and they will understand, and accept the science behind it. However, when the brain completely dies, and therefore so does the human being, that magically the essence of a person’s memories/language/sensory perception somehow transcend the body and become ethereal. It’s nonsense, of course, but poetic to us as humans. The ironic fault of our complex brain.
