Christopher Columbus first made landfall in the Americas on October 12, 1492 somewhere in the Bahamas, on an island which the natives called Guanahani and which Columbus renamed San Salvador. This date is a observed as public holiday in the United States as well as in many countries in South America. It is known as Discovery Day in the Bahamas, Day of the Americas in Uruguay and Day of the Cultures in Costa Rica. Many historians, however, are still asking the question "Who really discovered America?" Everyone knows that Native Americans were here long before Columbus arrived.
