Studies in Genesis 1
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.” (Genesis 1:20 ESV)
God created a physical planet in a hostile universe and filled it with life. He separated the waters forming oceans and lakes, rivers and streams. He set the boundaries of the atmosphere and made an environment capable of sustaining itself according to the laws of nature He put in place.
He created a perfectly balanced universe and a solar system within the universe to hold the life He created on Earth. Yet, by the fourth day, life on Earth is only food, green plants and vegetables and trees with their fruit. He covered the surface of the land with vegetation. He has also put food into the waters.
Now, on the fifth day, He creates animal life. He fills the waters with living creatures. He uses the word “swarm” which means to abound and to move while abounding. Plants and trees do not move. Animal life moves.
He does not create just a few creatures. He fills the seas with moving animals of an unknowable variety, from the smallest single cell animal to massive sea creatures. These creatures are designed to live and proliferate in water. They are not designed to survive on dry land.
He didn’t create only animal life in the waters. He filled the air, the atmosphere which surrounds the Earth, with birds and other creature which fly. Not a few birds or a few species of flying creatures but innumerable varieties and sizes and kinds. Like the fish, He uniquely designed these flying creatures to move through the atmosphere. We know these creatures rested on the land when not flying.
Early Earth was wondrous because God is wondrous. Occasionally, we discover the evidence of life from the earliest time. This evidence points to the creativity of the God of all.
