1492, Columbus set out for the first time, crossed the Atlantic Ocean westward to reach the American continent, mainly Cuba and other places, and inspected the local area. Of course, he thought he had arrived in India and named the island he found. Later, he came to the American continent four times, looking for countless gold in the East in his dreams, but he almost lost everything, but his contribution to the discovery of America should not be forgotten, which of course brought centuries of disaster to the American continent.
Of course, the discovery and naming of the new continent later had to mention another navigator, that is Amerigo. He followed the Portuguese fleet to the New World and made a detailed investigation in the northeast of South America, but the most important thing was his bold inference that Columbus arrived in the New World, not India. The concept of the New World fundamentally overthrew the concept of geography since the Middle Ages and broke through the shackles of authority. To this end, several French scholars revised the authoritative work of geography, Cosmology, and named the New World after Amerigo. Later, in order to keep consistent with the word formation of other continents, it was revised to Americana.
So who really discovered the South American continent? There's no way to make it clear. We can only know that Columbus was the first to arrive, and Amerigo was the first to put forward the concept of the new continent and name it itself. As for who discovered it first, it's hard to draw a conclusion. I don't know what you think of this matter. Welcome to discuss in the comments section!
