To begin, "you" do not exist as you believe you exist. There is no "you" because there is nothing that actually exists separately from anything else. To explain, this construct that you think is you is actually just a temporary collection of particles and energy; the universe barely if even acknowledges your existence. You were born, you will live and you will die. This doesn't mean that you ever existed, though. In fact, the fact that you will die is inevitable. If it is inevitable that you will die, then you are already dead, but you still never existed.
