Columbus was not the first European person to have discovered America. At the time of his voyage, Europeans did not know that the Americas existed. However, Leif Erikson, around 1000 AD had landed in present-day Canada. This discovery had no impact on European history and was not well documented. Columbus discovered America in the sense that he was the first person to create repeated exploration and contact with the New World. Another point is that Native Americans had been living there for thousands of years before he arrived. However, Native Americans did not record or contribute to the European record of history for obvious reasons. Columbus, therefore, "discovered" America in context of European history.
