What happens to us after we die? Where do we go? Is there any part of us that lives on? As obsessed as humans are with origin stories, we save our most fervent hopes and expectations for where we might spend eternity. In this episode, Morgan Freeman sets out to discover how belief in the afterlife has changed through the ages, how billions believe one man's death allows eternal life for all, and how the desire for immortality has influence scientists and inventors.

Is there some sense of God that all religions share? How has the identity of God changed over the millennia? Morgan Freeman embarks on a journey from the birth of monotheism in Egypt and Israel, to India, where Hindus worship millions of gods. He travels from a Houston megachurch to New Mexico where a Navajo girl communes with her divine ancestors. And, with the help of a neuroscientist, he searches for signs of God in his brain.
