Yeah. And you know that the current residents of France are decedents of the Gauls. But it doesn't give them any special insight to what was going on there 12 centuries ago - so much changes over time that it's just about the hardest thing to go back and really understand what they were thinking, how they were seeing the world, and what the world looks like to them. Their link to this past civilization carries with it heritage, which is not to be mistaken for history. I mean we know that the civilization was on real shaky ground before the Spanish arrived, long before. The lowlands in particular seemed to have done an Anasazi and just ceased to exist, but no reasons (or even legends) ever explained why.
So it's like Nostradamus - everyone who looks at it thinks they know, but really, does anyone? Did he even?
