In an important discovery, scientists have found more proof of old human footprints at White Sands National Park, New Mexico. These footprints were first talked about in 2021. They used special tests to know how old the footprints were, and the results were surprising. The footprints date back to an astonishing period between 21,000 and 23,000 years ago. This information changed what we knew about when people first came to America. We used to think they came later, but now it seems they arrived much earlier, even when ice blocked the way.

Some people were not sure about the tests used to find the footprints’ age. They thought plants in the water could make the tests wrong. But a new study in the journal Science used two different tests, and both said the same thing. So, we can be more sure that people really were in America a long time ago. This discovery is important because it helps us understand when and how people first came to America. We still have many questions, but these old footprints tell us a lot about how the first Americans lived and explored new places.
