Not to be a bummer, but nearly all of the cultures that have ever existed are gone. Nearly all of the languages that have have ever been spoken are gone. Nearly all of the civilizations that ever existed are gone. Nearly every single religion that has ever been believed in is gone. We’re the last remaining human species. Except in very rare circumstances there will be no proof that you ever existed in a thousand years, or more likely in a couple centuries, or even more likely once your grandchildren are dead. Your genes will survive a a dozen generations from now as scraps of junk DNA having no effect on your descendants or the course of evolution. Over a hundred billion people have lived these past fifty thousand years and you can probably name a few dozen who died before 1900, nearly all of them from whatever culture you were educated in. We’re here for a bit, the memory fades, and then it’s like we were never here at all, our existence as ephemeral the electrons I’m writing these words with.
