Is it a familiar story?
I've been told all my life that we had great thinkers and scientists since the ancient times. There were children cartoons about Archimedes, arab scientists and the likes when I was a kid in the '80s.
The younger generations are the target audience, who will believe these lies about your education. As old times slip from living memory, they are rewritten into a caricature of themselves to serve the current zeitgeist.
This is not an isolated case, e.g. this article [1] about appropriating babywearing fashion that tried to gaslight us into thinking Europeans simply had no way of carrying their children prior to strollers, and so we should feel appropriately guilty over using modern baby carriers based on "indigenous knowledge".
