The quoted comments are just a reminder that science does not explain everything. You may choose to wait to see if science can explain conscious awareness, or you are free to open your mind to the possibility that it could be the human soul which gives us conscious awareness and free will.
But you arbitrarily exclude other animals from your 'soul' hypothesis and yet they are clearly conscious also when not asleep. Gaping hole in your theory, this is, Alan.
Not to mention the inconvenient facts that you have failed to show what your soul is made of, how it affixes to a body, when it gets attached to a life, how it interacts with the material body, how come it doesn't show up on any instrumentation, where are souls before our body gets born, what about human hybrids, say a half neanderthal/half human does he get a full soul, or just a half ? what is the soul doing while the body is asleep ? That should keep you busy for a while, I've got more when you are ready.
