Everything dies eventually. We all know that. People, cities, whole civilizations. Nothing lasts. So if existence was just binary, dead or alive, here or not here, what would be the fucking point in anything? My mom used to say that's why we have memory. And the opposite of memory - hope. So things that are gone can still matter. So we can build off our pasts and make futures.
