Around the same time Egypt built its first pyramid, people in Peru were building similar structures in the ancient city of Caral.

We often think pyramids only belong to Egypt, but ancient humans on the other side of the world had the same idea. Between 2700 and 2600 BCE, people in the Supe Valley of Peru built up to 20 pyramid-like structures. This city, called Caral, is widely seen as the oldest city in the Americas. Because dating old stone is hard, we cannot say for sure who built theirs first, but both cultures reached for the sky at almost the exact same time.
