Closet racism. There is far more evidence that Europeans destroyed these cultures and ignored their advances, than there is proving this so-called myth.
See for example, the Australian FNP. They were far, far more advanced than European propagandists could allow anyone to imagine.
We are STILL uncovering major advances in these cultures today.
Other thank some claims about land management and herbal medicine, what were that not only more advanced in but FAR more advanced?
Ship building, metallurgy, literature, maths, chemistry, conflict management, law?
I am genuinely curious.
I am genuinely curious. [after all propagandists have prevented me from imagining, let alone knowing.]
There is much to learn about oneself once you drop the prejudice.
I'm not suggesting we haven't "advanced" beyond them now, but I am suggesting that we may have overlooked something in our race to the moon, and their 40,000 year old tradition of unbroken oral tradition ..
