I think that the Mayans and Egyptians and many other ancient cultures and even a whole lot of not-so-ancient cultures were, in a way, smarter than us because our reliance on technology has dumbed us down. For example, give your average architecture graduate a supply of stone and as much labor as they need, and do you think they could build some pyramids that are lined up not only with each other, but with important astronomical things? They’d be lucky to find anything more obscure than the moon or the Big Dipper, and let’s not even get into the difficulty they’d have doing the required math without a calculator...
No, I’m afraid I don’t get it.
