What did god do on the seven days of creation catholic?

In the Catholic understanding of the seven days of creation, God created the world in a structured sequence. On the first day, He created light, separating it from darkness. The second day saw the creation of the sky, followed by the emergence of land and vegetation on the third day. On the fourth day, God created the sun, moon, and stars; on the fifth day, He filled the waters with living creatures and the skies with birds; on the sixth day, He created land animals and humanity in His image. Finally, on the seventh day, God rested, sanctifying it as a day of rest.
