How Did the World’s First Civilization Fall?

Imagine you're building a super cool city with your friends, but then one day, your rival group attacks and takes over everything. That's what happened to the Sumerians, who were the first people in the world to live in big cities. They were really smart, they invented writing, math, even some of the earliest laws. But after a long war with another powerful group called the Akkadians, their cities slowly got weaker and weaker until one day, they just disappeared from history.
