How earlier cultures built huge structures—including kites that can only be fully seen from the sky—has remained a mystery This can only be fully seen from the sky struck me as somewhat odd, almost downplaying that all in all mammals and even simpler species are really good in basic navigation. I mean going from A to B and back among various lines if we've never done so before or even if we've done before but suddenly there are obstacles in between, is no problem for us. Unlike for, say, some of my chickens or simple AI models. Doesn't really matter if we can see the whole picture from the sky or not. In fact doing so without seeing the whole picture is exactly part of the skill? Or is this perhaps a comment about drawing such route? Ok that's a bit more specialist, but the accuracy in historic maps shows it's a skill we've had for a long time. And this dicovery might just be the earliest proof of it.
