Who were the first people of America

The first people of America, often referred to as Indigenous peoples or Native Americans, are believed to have migrated to the continent from Asia across a land bridge known as Beringia, which connected present-day Siberia to Alaska, during the last Ice Age, approximately 15,000 to 20,000 years ago. These early inhabitants established diverse cultures and societies across the continent, adapting to various environments from the Arctic tundra to the deserts of the Southwest and the forests of the East Coast. Over thousands of years, these groups developed unique languages, traditions, and ways of life. Some of the well-known Indigenous cultures include the Puebloans, the Iroquois, the Sioux, the Navajo, and the Cherokee, among many others. It's important to recognize that there is no single "first people" label, as numerous tribes and nations existed with distinct identities and histories long before European colonization began in the late 15th century. Today, there are hundreds of federally recognized tribes in the United States, representing the ongoing heritage and cultural diversity of Native American peoples.
