What people were the first to arrive in western areas?

The first people to arrive in western areas, particularly in North America, were Indigenous peoples who migrated from Asia via the Bering Land Bridge during the last Ice Age, around 15,000 years ago. These early inhabitants adapted to diverse environments across the continent, forming distinct cultures and societies. Over time, various tribes and nations emerged, each with their own languages, traditions, and histories. European exploration and colonization began in the late 15th century, significantly impacting these Indigenous communities.
