What Was America Like Before Columbus?

In 1492, Columbus didn't discover an empty wilderness. He walked into two continents already home to tens of millions of people—cities larger than London and Paris, pyramids rivaling Egypt's, roads longer than Rome ever built, and astronomers who predicted eclipses. These civilizations had been thriving for thousands of years before Europe knew they existed, developing writing, mathematics with a working zero, and razor-sharp calendars entirely on their own.

The First Americans: Footprints in Ancient Mud

The story begins with a mystery still being solved. For most of human history, the Americas had no people in them at all. Someone had to be first, and how they got there remains one of archaeology's most hotly debated questions.

At the peak of the last ice age, between 26,000 and 19,000 years ago, enormous ice sheets covered Canada and the northern United States. With so much water locked in ice, sea levels dropped by nearly 120 meters. In one corner of the globe, the seabed between Siberia and Alaska rose to become dry land—a vast plain called Beringia, stretching a thousand kilometers from north to south. This wasn't a narrow land bridge but a subcontinent with grasses, shrubs, and roaming herds of large animals.
