Several years ago, I came to the conclusion that the universe is a living entity and that people are akin to single brain cells within that living entity. And just as our entire body is considered to be alive, even though it is composed of material which would normally be considered lifeless (for e.g. water), everything in the universe as can be considered to be as alive as every aspect of our bodies. Is this belief a form of panpsychism?

Its an interesting question. It seems to me that humans are learning about how matter behaves when acted upon by the fundamental forces. But what matter is and how and why the fundamental forces operate the way they do seems to be beyond us. And I'm not sure we are making any progress in these areas, and maybe never will.
