A bog body is a person who died a long, long time ago and their body was found in a bog, which is like a wet and muddy area.
Back then, people didn't bury their dead like they do now. Some people believe that when a person died, they were left outside to be eaten by the animals or other things. But, sometimes the ground was too wet for them to be buried in, so they were left in the bogs instead.
The cool thing about bog bodies is that the bogs help to keep the bodies well-preserved, like a time capsule. So, scientists and archaeologists can learn a lot about history and people from these bog bodies.
However, it's important to remember that these bog bodies are also people and should be treated with respect. They were once someone's friend or family member and deserve to be remembered as such.
