Why is there a debate of who discovered America?

There are two different kinds of discovery, because one is the discovery of the native Americans and the other discovery is through Christopher Columbus. The native Americans were the first people who came to America, they discovered the land on the search of food. They came from Asia over a “land bridge” to America. When they noticed that the diversity of food is much bigger in the south than in the north they expand more and more into the south. On this way they colonize the whole country. The second discovery was with Christopher Columbus he discovered America from the european site. He was the first european man who discover America and announced America in Europe. This is what most of the people call as “The discovery of America”
