Then God said, “Let the waters teem with swarms of living creatures, and let birds fly above the earth in the open expanse of the heavens.” God created the great sea monsters and every living creature that moves, with which the waters swarmed after their kind and every winged bird after its kind; and God saw that it was good. God blessed them, saying, “Be fruitful and multiply, and fill the waters in the seas, and let birds multiply on the earth.” There was evening and there was morning, a fifth day. Genesis 1:20-23 NASB
On the fifth day of creation, the earth was ready to support animal life. God spoke into existence: water, soil, air, plants and fruits for food, as He did with the sun to give light and warmth to the earth. God systematically and orderly created the earth and all that is within and upon it. God was meticulous in every detail, painstakingly creating an environment into which He could place every created creature and man.
Habitats were created to support what God had in mind with minuscule details that had to be right, such as the temperature of the water to support precise kinds of fish and air temperature for winged creatures.
Now God created the Earth’s first inhabitants – the animals that live in the sea and fly in the air. Once again, He simply commanded them to come into existence. When God spoke, suddenly the sea was teeming with every kind of creature which lives there – small, tiny sea life, medium-sized fish, larger fish, and the larger creatures, like whales.
Suddenly, at God’s command, there were all species of flying creatures, birds, flying insects, bees and bugs; as well as bats, and flying creatures.
God made these many species of the air with different kinds of wings. There were creatures with wings covered in feathers; insects’ wings are made of membranes or thin scales; bats’ wings are made of skin stretched over long arm and hand bones. Beautiful, wondrous creatures.
God was pleased with all He had created on Day 5. Not only did He say it was good, He also blessed the fish and the birds, and commanded the fish to reproduce to fill the seas and for the birds to multiply on the earth.
God is a God of reproduction, not stagnation. God’s unlimited wisdom, knowledge and power are seen clearly in His creation of everything within a short period of time. He wants us to be active in life also!
