We don't really understand most of what's happening in the cosmos. Is there any afterlife? Who knows.
I'm using the afterlife as a backdrop against which to explore the joys and complexities of being human - it turns out that it's a great lens with which to understand what matters to us.
It is only through us that God lives. When we abandon him, he dies.
I think what a life in science really teaches you is the vastness of our ignorance.
