So, a really long time ago there were some people who lived by the sea. One day, they decided to go exploring and they started traveling to different places.
But sometimes, they would get into fights with the people who lived in the places they went to. And pretty soon, people started calling them the "sea peoples" because they came from the sea and fought a lot.
These sea peoples were very fierce and strong, so people were afraid of them. They would attack villages and take away things like food and treasure.
Eventually though, the sea peoples stopped doing this and it's not really clear why. Some people think that maybe they found better ways to make a living besides fighting all the time.
But even though they stopped fighting, people still remember the sea peoples as a group of people who were really good at sailing and were pretty scary when they wanted to be.
