Welcome to Apologia: Flying Creatures! We're going to have an amazing year learning about God's creation!
" And God said, "Let the waters swarm with swarms of living creatures, and let birds fly above the earth across the expanse of 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. Genesis 1:20-21.
