God Fills the Seas and the Air With His Creatures

And God said, "Let the waters swarm with swarms of living creatures, and let birds fly above the earth across the expanse of the heavens." So God created the great sea creatures and every living creature that moves, with which the waters swarm, according to their kinds, and every winged bird according to its kind.

And God saw that it was good. And God blessed them, saying, "Be fruitful and multiply and fill the waters in the seas, and let birds multiply on the earth." And there was evening and there was morning, the fifth day.

(Genesis 1:20-23)

The creation of the sun, moon and the stars came after the creation of the plants and trees. The process of photosynthesis now began in the living plants.

Next God created the birds and sea creatures after their kinds. "Birds, as a group, have been extensively studied. Scientists believe that the estimated number of bird species alive today (between 9,000 to 10,000) is a relatively good approximation of the actual number", writes Laura Klappenbach. Some of the best estimates of the number of species of fish puts it at 32,500. Since the Bible uses the term "great sea creatures," the whales and aquatic and marine mammals were also created then, including sea-dwelling dinosaurs and avian dinosaurs

Each species of fish and bird, marine and aquatic mammal, avian dinosaur, and aquatic dinosaur was created on day 5. The Creator programmed each species to be fruitful and to multiply.
