Then God said, “Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds.” And it was so. The land produced vegetation: plants bearing seed according to their kinds and trees bearing fruit with seed in it according to their kinds. And God saw that it was good. And there was evening and there was morning – the third day.
God created kinds that were distinct, each complex organism made for a different role; each one would become part of an interconnected web of life. God saw that the many different forms of created life were good. Good things are the things done by God who brings perfection to all that He does.
