This is super dumb. People always act like airplanes were just "invented" one day, especially by the Wright brothers.
This isn't the case at all, decades before there were people doing (powered) gliders and getting pretty far. Propellers were also well known at that point and a lot of people knew if you could get enough power to weight ratio you could get something that flew. Multiple people were working on small engines with a lot of output, combined with a light airframe and a death wish. Controlling the plane was also a huge challenge people were working on, which was the same for gliders and planes a like.
Sure the Wright brothers got there first, according to history, but many people followed soon after with their own designs. It was more of a humanity's capabilities to build such a thing caught up with their imagination and thus it was a thing.
