Children in America who attend some sort of religious school, even before going to secular school, may learn some limited sort of ancient history. Ancient in that it concerns purported people and events from millennia ago. Limited in that some number of those people and events, however instructional and enlightening, may be of some historical question.
There is other ancient history worth teaching our kids early, and catching up with ourselves, just in case we missed it in our own education. There are continuous civilizations all around the world that have been ongoing, in the same place, also for millennia.
China, for example. Or India. Or the native populations in the Americas. This is where education should start, before we start talking about admittedly important people arriving on these North American shores and establishing an admittedly important nation just a few centuries ago.
Why? Because it would give us a sense of perspective on what we have, or have not, achieved so far. And because it would give us a missing sense of the scope of history, in that everything comes and goes. Which you could learn from the history of China. Or you could learn from reading the I Ching, the book about things changing, written in China millennia ago. Or if you prefer something more Western and familiar, from reading the Bible itself. A time for every purpose, it says. And so it goes.
