Or maybe you just have what was stored in various nuclear shelters at that time ? That could be even more confusing!
In one unused shelter here in Brno the numbered stones of a medieval chapel are stored since it was demolished long ago. In another shelter in Prague you can find the complete archive records of the Prague 4 city administration.
Any aliens discovering this would inevitably reach the conclusion that humans had a lot of respect to both honoring their past & for comprehensive bureaucracy. So much indeed, that when the end came, they decided to forego the temporary safety of their shelters and let this legacy of their culture survive instead!
