Daily Reminder that Columbus was an idiot and was not the first person to know the earth was round. In fact, he used a millennium old greek reference to determine the circumference of the earth but failed to convert the older measurement to the modern units of measurement, leading him to believe the world was much much smaller than it actually was: which is why the much more intelligent Spanish monarchy advisors refused him expedition funding and forced him to go to England, instead. He still was not even the first to discover the Americas, the Spanish beat him to it a second time and the Polynesians and ancient migrants had been living there for thousands of years. The only thing Columbus actually succeeded in doing was rape and genocide of the indigenous people: one of the worst human scum to be remembered throughout history.
