The term "afterlife" suggests that are only two lifes: a llfe and an afterlife. Sorry, but that seems to be pure nonsense. Either you are a materialist and do only believe in what you can see or touch or you believe that this world is spiritual world. Either way there's no room for an afterlife. Religion, in my opinion, is a barrier in your mind, something that stops you in midflight. There are no gods, neither Christian, Islamic or whatever. But from the experiences I've made I can ruled out that this world is material. All of our greatest philosophers will agree. I summon Plato, Kant, (the much underrated) Schopenhauer, Wittgenstein, Lao-zi and Chuang-zi as witnesses. They all more or less agreed that we make up this world in our minds, it has no reality of itself. Edgar Allan Poe, the greatest poet that has ever lived, put it this way: All that we seem or see / is but a dream within a dream.
