How Did People First Reach the Americas?

People have lived in the Americas for thousands of years. During the last Ice Age, lower sea levels exposed a region called Beringia, a stretch of land between what are now Siberia and Alaska. Some early travelers moved through this region, while others may have traveled along the Pacific coast by boat. Researchers continue to study when and how these journeys happened. Migration means moving from one place to another. These journeys happened over many generations. People traveled to find food, water, and places to live.

At White Sands in present-day New Mexico, ancient human footprints provide evidence of people living there roughly 23,000 years ago. The footprints were left by people walking across wet ground long ago. Over time, the footprints became preserved in the earth. They help researchers learn about when people lived in North America. These discoveries also show why historians may change their explanations when they find new evidence.

How Do Indigenous Peoples Explain Their Origins?

Indigenous nations have their own origin stories. These stories explain how people understand their beginnings and their connection to the world around them. The Haudenosaunee (pronounced hoh-deh-noh-SHOW-nee) are a group of Indigenous nations from the northeastern part of North America. Their name means “People of the Longhouse.” They formed a union called the Haudenosaunee Confederacy. Its six member nations are the Mohawk, Oneida, Onondaga, Cayuga, Seneca, and Tuscarora. The first five nations formed the original confederacy. The Tuscarora joined later. One Haudenosaunee origin story tells about Sky Woman and Turtle Island. These stories are important traditions that people still share today. Different Indigenous nations have different origin stories.

Scientists study old objects and places to learn about the past. Archaeologists are people who do this work. Indigenous communities also share knowledge through oral histories. Oral histories are accounts of the past told from one person to another. Families may share them across many generations. Both kinds of sources help us learn about history.

Why Were Early Communities Different?

The first peoples of the Americas did not form one single society. Over many generations, communities developed different languages, traditions, and ways of living. Some traveled seasonally to find food. Others established long-lasting settlements. People adapted to their surroundings while making their own decisions about how to live. For example, some communities lived near rivers and used fish as a food source. Others hunted animals or gathered plants. The many ways people lived show how diverse early Indigenous America was.

Why It Matters

American history began long before European explorers arrived. Learning about early migration, Indigenous knowledge, and diverse communities helps us understand that the Americas already had rich histories before 1492. Indigenous nations are still here today. Their histories are part of American history.
