How did people in ancient times explain the origin of our planet?

The most common hypothesis for the origin of the Earth in the ancient world was the theory of spontaneous generation (primary chaos). It was put forward in Ancient Egypt, China, Greece. The second is the theory of creationism. She believed that the creation of life was a supernatural being. For a long time, there has been an assumption that the earth is supported by three whales that swim in the ocean. The ancient Greeks saw the earth as a flat disc. For the first time, the ancient Greek scientist Pythagoras announced the sphericity of the Earth.
