Cairo has been around for a very, very long time. In fact, people have been living in Cairo and the surrounding area for over 6,000 years! That's a really long time!
The first people who lived in Cairo were farmers who grew their crops along the Nile River. They built small villages and homes out of mud and straw. Over time, people came from all over the world to live in Cairo, including the ancient Greeks and Romans.
As time went on, Cairo became a very important city. It was ruled by many different kings and sultans, who built huge palaces, mosques, and other important buildings. They also built walls around the city to protect it from invaders.
In the 1800s, the British took over Cairo and made it a colony. This meant that they took control of the city and ran it themselves. They built many new buildings, including banks and government offices.
Today, Cairo is a bustling city with millions of people living there. It's famous for its pyramids, ancient ruins, and museums. Despite its long history, there is still so much to see and learn about Cairo, and people from all over the world come to visit this amazing city.
