**Ancient Humans Arrived in the Americas Much Earlier**
New discoveries are changing our understanding of how humans first arrived in the Americas. Archaeologists have found evidence that people lived in North and South America much earlier than previously thought.
In Brazil, researchers found a carving on a giant sloth bone that is about 25,000 to 27,000 years old. This suggests that humans were living there during the Ice Age. A similar find was made in Uruguay at an archaeological site called Arroyo del Vizcaíno. The fossils found there indicate that humans lived there around 30,000 years ago.
These discoveries are important because they push back our understanding of when humans first arrived in the Americas. Historians had previously thought that humans arrived about 15,000 to 20,000 years ago. These new finds show that people were living in the Americas for thousands more years than we previously believed.
