Even though we can say that Columbus did not discover anything new, why is his voyage across the Atlantic still seen as one of the key events in human history

Christopher Columbus: Early Life

Christopher Columbus, the son of a wool merchant, is believed to have been born in Genoa, Italy, in 1451. When he was still a teenager, he got a job on a merchant ship. He remained at sea until 1476, when pirates attacked his ship as it sailed north along the Portuguese coast. The boat sank, but the young Columbus floated to shore on a scrap of wood and made his way to Lisbon, where he eventually studied mathematics, astronomy, cartography and navigation. He also began to hatch the plan that would change the world forever. The First Voyage

At the end of the 15th century, it was nearly impossible to reach Asia from Europe by land. The route was long and arduous, and encounters with hostile armies were difficult to avoid. Portuguese explorers solved this problem by taking to the sea: They sailed south along the West African coast and around the Cape of Good Hope.But Columbus had a different idea: Why not sail west across the Atlantic instead of around the massive African continent? The young navigator’s logic was sound, but his math was faulty. He argued (incorrectly) that the circumference of the Earth was much smaller than his contemporaries believed it was; accordingly, he believed that the journey by boat from Europe to Asia should be not only possible, but comparatively easy via an as-yet undiscovered Northwest Passage.
