What discoverer s proved Columbus wrong when he said he landed in Asia?

Ferdinand Magellan's expedition in 1519-1522, which was the first to circumnavigate the globe, provided evidence that Columbus had not reached Asia but rather the Americas. Additionally, explorers like Amerigo Vespucci, who mapped the coast of South America, argued that the lands Columbus encountered were part of a new continent, distinct from Asia. Their findings ultimately led to the recognition of the Americas as separate from Asia.
