Is their any scientifically sound reason to believe in an afterlife? Because the more I look into it, the more convinced I am that consciousness is created by the physical brain and once the brain dies, our consciousness also dies. This makes things like the mind-body problem very easy to solve.
And yet people, even educated ones, keep acting like this is still up for debate. What am I missing? Are the educated believers in an afterlife just grifting? I'm not afraid of an eternal dreamless sleep, but if there is a valid reason to believe that there is something beyond this existence that I can take part in, I would love to know.
