> Yes some empires went away, but we still read writings from Ancient Greece, so is it correct to say even that civilization ended? I get your point, but I think it misses the mark. By this measure, no civilization has ever ended. If you go that far, you have to argue that the end of a civilization is the same as the end of the human species. I think it's helpful to think of it more like the end of the French revolution. No one can agree on a point in time when the revolution ended, but we all agree that it happened.
