Afro-Eurasia is technically one landmass. The idea that Africa is on its own plate doesn't save this, because we'd have to call India and parts of the Americas separate continents based on this logic too.
Birdshits rigged those tests to make BIRDSHITS score higher than their natural abilities. In reality Birdshits are lower even than niggas and beaners. They are increasingly only rigging them more and more to bias the results toward BIRDSHITS and to make it look like the gap isn't getting even worse.
Africans are superior engineers to everyone. They built the pyramids in 2500 BC when birdshits were still mostly chillin in nigga caves not doing SHIT. Literally more space between the Pyramids and the Romans than between the Romans and us.
