We see how as part of creation, God names the things He creates, implicitly also creating a system of language. As the foundation of our intellect, language is important to us to be able to understand concepts and develop coherent thoughts. We also see how God created vegetation in their own kinds with seeds, to be able to reproduce and provide a source of food for the coming creations.
Then God said, “Let the waters below the heavens be gathered into one place, and let the dry land appear”; and it was so. God called the dry land earth, and the gathering of the waters He called seas; and God saw that it was good. Then God said, “Let the earth sprout vegetation, plants yielding seed, and fruit trees on the earth bearing fruit after their kind with seed in them”; and it was so. The earth brought forth vegetation, plants yielding seed after their kind, and trees bearing fruit with seed in them, after their kind; and God saw that it was good. There was evening and there was morning, a third day.
