I can remember thinking about this when I was 7. It's an unanswerable question but it's still interesting, I believe: Can we relate every person on Earth by a tree of acquaintances? That is if we were to construct a stem diagram in which the first branch relates me and all the persons that I know personally, and the second branch the people I know with all the people they know, and so on, would we end up including every person on Earth in that construction?
