That was the case for me too... even the longest-lived people I would ask questions about still didn't know anything about the oldest lost civilizations. It's amazing how they can just vanish that thoroughly while still leaving ruins and information and learning behind...

I already always thought the world must be a really big place, and then to come here and realize that it's even bigger than just one world...

Did you learn anything from the seraphim on things you didn't read about in books?
