there is no evidence the brain produces consciousness, and this idea is central to the philosophy of Physicalism. Rather, what I resonate with is the reality that ALL is conscious, all is alive. That we grow out of intelligent nature, die into it and regenerate , and this process is cyclic and eternal (not bound by linear concept of time). HOW could subjective sonciousness suddently come about from 'unconscious' matter? if you want to look at the philosophical position that challenges the physicalist philosophy, I recommend Radical Nature: Rediscovering the Soul of Matter, by Christian Der Quincey https://www.amazon.co.uk/Radical-Nature-Rediscovering-Soul-Matter/dp/1931229155
