Don't hold back, tell us how you really feel. ;')
I just love these "We invented X-Y-Z before you eeevil Whites did" stories. They're usually about cultures that did absolutely nothing with the knowledge. The Chinese may have landed in North America before the Europeans did; but so what? They never exploited that knowledge. The Africans may indeed have had knowledge of advanced mathematics. But what came of it? Nothing; they are barely Iron Age societies. What technology they have came from the outside. The Arabs go one and on about inventing the zero; but their level of technology (a tangible expression of their alleged math skills) is a zero. They invent nothing.
Having a bit of knowledge isn't quite so important as using that knowledge.
