Atheism, or a disbelief in a lack of an afterlife is as much a belief system as theism. There is no way to prove it one way or the other, so I still caution against subscribing to such a hardcore position. Especially because that afterlife does not need to be immediately after death but could be in the far future, but you would have no concept of time until then. I don't see why it's so fantastical to think that it's possible that eventually a sufficiently powerful computing system will be developed in the far future and we will all be recreated in simulation in it, from which in our own perspective it will seem and be for all practical purposes an afterlife. In fact maybe the eschatological doctrines of many world religions throughout history is just to motivate mankind to reach such a technological state and then effective "revive the dead".
