Summary:
- Archaeologists have discovered ancient human footprints in New Mexico, United States, that are estimated to be over 23,000 years old.
- These footprints provide evidence that humans were present in North America much earlier than previously thought, challenging the widely accepted theory that the first people arrived in the Americas around 13,000 years ago.
- The discovery of these ancient footprints could rewrite the history of human migration and settlement in the Americas, and offers new insights into the earliest inhabitants of the continent.
