God created the world in seven days. Some argue that maybe each day took millions of years and the creation continues up to the present time. The first day the square in the center of the painting is according to the big bang theory that started the creation of the universe.
Then galaxies formed stars, planets developed, and primitive life on Earth began. On another day, vegetable and fruit trees started to grow., Creatures of the sea evolved to be able to live on dry land. Then man was created. Day by day, generation after generation, man became more civilized and grew in knowledge and technology. In the future, man will travel to other planets and live under the sea.
It is a very detailed painting and the way I transitioned from one ecosystem to another is wonderful to view.
