Creationism is the belief that God created the world as it is today. It is an old idea that has been around for thousands of years. In the Bible, it says that God created the world in seven days. This means that everything - the stars, the plants, the animals, and even people - were all made by God within seven days. Over the years, people have come up with different theories about how God created the world. Some people thought that God made each creature separately, while others believed that God made everything at the same time. In the twentieth century, a group of scientists started a movement called “Intelligent Design,” which said that the complexity of the natural world could only be explained if God had a role in its creation. Today, some people still believe in creationism, while others believe in the theory of evolution.
