Ok. It is after all about the biochemical cocktail in our brains. And isnt that a fascinating thought? All we think, all we do, all our body does without our knowledge; all our hopes and dreams and aspirations; our fears and regrets and doubts; our feelings, emotions and perceptions are all a bunch of chemicals and electrical impulses in our brains. The mind is what the brain DOES. We have arisen through a fantastic process of supernovae explositions and gas cloud coalescence and planet formation over billions of years until evolution produced our species and the matter that constitutes us came together to form us. As Neil Tyson [and Carl Sagan] said: "Not only are we a part of the Cosmos, the Cosmos are a part of us". Who says Atheists cannot be spiritual or revel in the beauty and grandeur of the universe.
