The concept of the afterlife is based on the human ego. We as a species are special and we have souls which will go on to live for eternity after we die. What we have deemed the soul, however, is just a way for us to label our consciousness and the complex workings of the brain. I believe we are not different from any other animial and the soul is just an illusion that ends with death.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
