Anne Rice said this quote

I realized aloud in the midst of saying it that even when we die we probably don't find out the answer as to why we were ever alive. Even the avowed atheist probably thinks that in death he'll get some answer. I mean God will be there, or there won't be anything at all.'But that's just it,' I said, 'we don't make any discovery at that moment! We merely stop! We pass into nonexistence without ever knowing a thing.' I saw the universe, a vision of the sun, the planets, the stars, black night going on forever. And I began to laugh.'Do you realize that! We'll never know why the hell any of it happened, not even when it's over!' I shouted at Nicolas, who was sitting back on the bed, nodding and drinking his wine out of a flagon. 'We're going to die and not even know. We'll never know, and all this meaninglessness will just go on and on and on. And we won't any longer be witness to it. We won't have even that little bit of power to give meaning to it in our minds. We'll just be gone, dead, dead, dead, without ever knowing!
