no one seems to be able to give a reason to that holds up. if it's happiness, then happiness will vanish with death soon enough, making it pointless as it will not last. unless there's an afterlife, in which case life just delays access to eternity. if the point is to learn, or to discover the meaning, what happens when we finally reach those goals? existence would be meaningless. i could go on, but in short, for any goal to be reached, striving for it must come to an end. Once given meaning, life becomes pointless.
