The Ontological Point
One book which I have read which is relevant to the discussion which you have raised is, 'The Corpernicus Complex:The Quest for Our Cosmic (In)Significance,' by Caleb Scharf, (2014). In this, the author argues,
'our specific human biology, its evolutionary history, and its connections to our planetary circumstances could well be unique_ if measured with a fine pair of calipers. But this does not have to imply that life_even complex life_ can't reach similar states by following other pathways. We could be special yet be surrounded by a universe of other complex, equally special life-forms that just took a different trajectory.'
However, I am not sure that I find his argument fully convincing and I was a bit disappointed by the book because it seems to focus on bacteria as life. He does not look at the issue of human consciousness. I suppose it just calls for us to question our significance. I have interacted with you enough to be aware that you don't have any sense of us having a 'sacred destiny', but in thinking about what you have said and Scharf's ideas, I do think it just important for us not to read too much into our place in the universe. We could become too inflated about being our evolutionary status. However, I do believe that the evolution of our consciousness is a territory for exploration in its own right, but that is probably outside of your thread discussion.
