Okay, so Old Europe is a fancy way of talking about something that happened a loooong time ago in a place called Europe. It's like talking about your grandma when she was young - we're thinking about a time a long time ago!
Archaeologists are like detectives, they try to figure out what happened in the past by looking at the things left behind. So they've been digging up different parts of Old Europe to find things that people from that time used or made.
You know how you have toys and clothes that you love to play with? People in Old Europe did too! But instead of toys, they had things like clay figurines and jewelry. Archaeologists have found these things buried in the ground, and it helps them understand what life was like back then.
Old Europe was also a place where people built really cool things like houses and temples. They used all sorts of materials like mud, clay, and stones. Archaeologists have found pieces of these buildings and have been able to put them back together like puzzles! It's like if you had a puzzle box with a picture on the front, but it was all broken into pieces inside. You'd have to use your detective skills to figure out how to put it back together, and that's what archaeologists do!
So, basically, Old Europe is a time a long time ago in a place called Europe. Archaeologists are like detectives who dig up things left behind to help us learn more about that time. They've found toys, jewelry, and even buildings that people from that time used and made!
