A civilian is like a regular character in a big movie. Imagine the movie is about superheroes and the superheroes are like the soldiers or police. The civilians are everyone else, like the people who live in the city and go to work or school. They are not the ones fighting the bad guys; they are just living their everyday lives.

Think of a big game of cops and robbers. The cops are the ones trying to catch the robbers, and the civilians are the kids who are playing on the swings or building sandcastles. They are not part of the game; they are just having fun and doing their own thing.

In a parade, the people marching in uniforms are like the soldiers, and the civilians are the ones watching the parade, clapping, and cheering. They are part of the crowd, enjoying the show but not marching themselves. Civilians help make the world feel normal and happy because they do all the everyday things that keep life going smoothly.
