Which area remained unihabited until 1425?

The area that remained uninhabited until 1425 is often referred to as the "New World," specifically parts of the Americas. While indigenous peoples had been living in various regions of the Americas for thousands of years, large areas, particularly in what is now modern-day North America, experienced European exploration and colonization only after 1425. This period marks the early stages of European contact, which would eventually lead to significant settlement and cultural exchange.
