Okay kiddo, imagine you are playing a game where you draw a picture of the world, with animals, plants, and people inside of it. This drawing is called a cosmogram.
A cosmogram is a picture or diagram that shows how people see the world and their place in it. It's like a map that shows where everything belongs, like the stars in the sky, the ocean, the mountains, and the animals that live there.
People have been making cosmograms for thousands of years. Different cultures have different cosmograms, because they have different ways of understanding the world around them. Some may have pictures of gods and goddesses, while others have symbols that represent the elements of nature.
In short, a cosmogram is a picture of the world that helps people understand their place in it, and different cultures have different ways of drawing it.
