Quote by John Green (The Fault in Our Stars)

There will come a time where all of us are dead. All of us. There will come a time when there are no human beings who remember that anyone ever existed or that our species ever did anything. There will be no one left to remember Aristotle or Cleopatra let alone you. Everything that we did and built and wrote and discovered will be forgotten. And all of this will have been for nothing. Maybe that time is coming soon, and maybe it is millions of years away, but even if we survive the collaps of our sun, we will not survive forever. There was a time before organisms experienced conciousness and there will be a time after. And if the inevitability of human oblivon worries you, I encourage you to ignore it. God knows that's what everyone else does.
