I'm sure all those Africans invented a game with a fucking Bishop and a Horse, two things that had to be imported into their continent later.

Also they'd probably do a lot better if they didn't get lazy and copy paste the same name for a bunch of inventions that are so far removed from each other's fields that it strains any credibility that someone would be competent in both.

Like in what world is this Morgan guy just casually inventing a fucking gas mask and a traffic signal. Why is he dabbling in both.
