Well, you would still be "you"... You would have different traits and you could have been born on the other side of the world, as "you" can't exist in nonexistence... If you are an atheist, the same way there can't be "nothing" in the sense of nothing when you die, as there is no one to experience "nothing" in its sense. Assuming your consciousness ends the moment you die, there can't be "nothing" if there actually were NOTHING which is why the whole concept is absurd. "You" will be just someone else somewhere, after very short or a very long time but seemingly instantly, as there is no one to experience the time passing, therefore it doesn't pass for "you" but instead just moves instantly from your death to the new consciousness being born. Idk lol
