Okay kiddo, let me explain the Neolithic period in the British Isles like you're five years old!
Long, long ago, when there were no supermarkets and people had to hunt and gather their own food for survival, things were very different. This period of time is called the Neolithic period and it happened in Britain thousands of years ago.
During this time, people started to move away from just hunting and gathering and began to farm their own land. They learned to plant seeds, grow crops and raise animals, which meant they didn't have to rely on just finding food in the wild anymore. They also started to build homes that were more permanent and would last many years.
The Neolithic people in the British Isles were really smart and invented many things we still use today, like the wheel and tools made from flint. They also started to build big stone structures called megaliths, which were used for different purposes such as tombs or places of worship.
One of the most famous megaliths is Stonehenge, which was built in England over 4,000 years ago. It's still a mystery how the Neolithic people managed to move the huge stones and put them in place, without any modern technology!
Overall, the Neolithic period was a time of great change in the British Isles, where people started to live in a more settled way and invent new things that would shape the world we live in today.
