Who was the first person to go Jamaica?

Your question is based on a false premise. Jamaica is a Caribbean island, and there is no evidence to suggest that a specific individual was the first to visit or "go" to Jamaica. The history and settlement of Jamaica involved various groups, including the indigenous Taíno people, Spanish explorers and settlers, British colonists, and enslaved African people. The island has been inhabited for thousands of years, with a rich history that predates any single person's arrival.
