Stone objects recovered from deep inside the Nequatto caves in Southern Mexico hint that humans may have arrived in the Americas as early as 30,000 years ago. This date is hotly debated among archaeologists, with many initially placing the first human presence in the Americas at around 13,000 years ago, as ice sheets receded and migration routes from Asia opened up.

And the new analysis of stone artifacts, including blades, projectile points, and rock flakes, interspersed with bits of charcoal dated to some 30,000 years old, suggests humans likely arrived in the Americas before glaciers began to melt. Studying the cave suggests it could have been hospitable tens of thousands of years ago, as the region was likely much cooler, wetter, and greener than it is today.
