But the future Alien [or even human historian] would have to realise that what they are walking on isn't a Zen Garden but the entire repository of human knowledge. Would they? Unless they know about DNA encryption, it will look a lot like gravel to them. Archivists are looking at going back to basics and using a form of microfiche etched on to very stable glass. It's a mechanical system that should mean the information is recoverable given only a limited technology.But otoh, this is interesting: Scientists even now are able to encode a whole book or multiple books in very tiny structures, like synthetic DNA. Something the size of a small pebble could contain a vast store of history. So even if an apocalypse wiped out our WWW and computers all over the world, whatever, or simple passage of time wiped those out, a future historian might need to find only one such tiny storage device and could still have a vast amount of data about our culture.
It is the other end of the discussions on how to mark Nuclear Repositories as dangerous places for a quarter of a million years. They are looking at making the land itself give off an eerie feeling with infra-sound so you feel ill at ease close by. Words and signs will erode or become unreadable but if you can manipulate landscape to make people not want to live there...
