"...consciousness is not a thing, it is a process the brain does..."

Research into consciousness using single celled creatures has showed that they learn, remember, and make conscious decisions, and single celled creatures do not have brains, which are networks of cells, primarily neurons. Search up research on running slime molds through mazes, and you will have to concede that brains are not the source of consciousness. Look at my reply to the OP above and see the other links and information, DYOR on it, and see if you can avoid the conclusion that brains (and our 'selves') are useful tools megafauna can apply to manage the actions of their physical bodies. I'd be interested in hearing any arguments you could make countering my understanding that brains are simply mechanisms consciousness uses to manage bodies comprised of 10's of trillions of cells without having to hold endless meetings of all the conscious cells that must act when we walk, eat, or talk.
