You know how people have different ways of living and doing things? Like how some people wear different clothes or eat different foods? Well, a long, long time ago, there were people who had a way of living that we call "Swiderian culture."
The Swiderian culture was a group of people who lived in Europe around 11,000 to 8,000 years ago. They were called that because their tools were found in a place called Swidry Wielkie in Poland.
What made the Swiderian culture so special was their cool tools that they made. They would take rocks and make them into sharp points called "microblades." These blades were very thin and sharp, like the edge of a razor, and they were used for things like hunting, cutting food, and making other tools.
The Swiderian people also had a specific way of living. They were nomads, which means they didn't stay in one place for a long time. They moved around a lot, following animals to hunt and finding new places to live.
Even though the Swiderian culture existed a long time ago, we still know things about them because of the artifacts and tools they left behind. Scientists study these artifacts to learn more about how people lived back then, which helps us understand the past and the world today.
