My opinions about blacks having an extra leg muscle. Some whites may have it too. Robots?????

I heard a story of a white guy who could jump over a volley ball net, either they were lying or robots exist. I have seen countless scenarios myself as well where humanoids were able to surpass my abilities. Could these THINGS be actually reenacting the movie "they live"¿?¿?¿?¿? That would be horrible if so.
