In short
Around 10,000 BCE, the Nile River underwent a dramatic shift in its flooding patterns, transitioning from the arid conditions of the last ice age to a wetter climate phase. This climatic change transformed the river valley from marginal scrubland into a fertile floodplain, setting conditions that would eventually allow human settlement and agriculture to flourish along its banks.
How it unfolded.
The five-minute version
What actually happened.
The Nile is a major north-flowing river in northeast Africa which empties into the Mediterranean Sea. At 7,088 kilometers (4,404 mi) long, it is the longest river in the world, although the volume of water it carries is much smaller than other major rivers such as the Amazon or the Congo. The Nile has played a central role in the environmental, economic, and cultural history of Africa for millennia.
