I thought the discovery of Wakanda had settled all the ancient African technology issues.
Wakanda has western-made old tires and western-made cigarette lighters, along with western-refined gasoline. That's their African technology.
In Wakanda they use tribal drumming to raise blocks and move them hundreds of miles.
Then they call on the spirits of the great engineers to design the building, and the spirit of the great stone cutters to perfectly carve the stones.
This amazing technology was lost when the evil white people invaded and demanded obedience to their useless Gods....
(That is what they teach these days in school, right? ;-) )
