Keep in mind that what's considered "genius" is relative to what existed previously that was built upon.
Today, a child can set a fire or make a wheeled cart out of paper, but millennia ago in primitive times, the invention of fire and the wheel were among the most brilliant discoveries ever made.
Even in modern times, traveling faster than the speed of sound was considered impossible. Gremlins awaited us on the other side. But leave it to the cream of the crop physicists and engineers on planet Earth (not to mention a genius test pilot) to figure out how to navigate around the impossible which, eventually, led to a commercial airline that routinely carted the more affluent all around the world on a daily basis.
For that matter, how long did mankind think it was impossible to fly at all, until the Wright brothers came along?
Likewise, adding a couple of levers to a hand-powered potters wheel to make it foot-powered so you could free up both hands sounds like a school shop project today, but it took the Dynastics 1000 years to figure that out, and even then they got help from the Hyksos, et al. Same with the 2-wheeled chariot.
Genius is relative.
How can any of us ever know, when all we can do is think?
