I don’t believe in such a thing as life after death, but I wonder what exactly happens to your consciousness when you die. During your whole life, there’s never a “gap” from your point of view: you fall asleep and, next thing you know, you either dream or wake up. The same happens when you lose consciousness—your memory is always a continuum in which you were always conscious, as if the periods in which you were not had never existed. People suffering heavy physical damage which rendered them unconscious for a long time have reported to experience the same, some even resuming at the hospital the motions they were previously making as soon as they woke up again. It’s impossible to know how our consciousness came into being, because we have no memory farther back than a certain point in our early childhood. For all we know, it could be the same consciousness that at some point experienced the life of another living being, and we can’t know, because memory definitely isn’t preserved beyond the death of the brain cells it was encoded in.
In fact, none of us can even know if other people have a consciousness just like our own, or just behave as if they did (philosophical zombies).
Oh, and I do think belief in an afterlife can be very harmful, because it encourages wasting the only true life we are sure to have.
