My understanding of the meaning that is being conveyed is how God’s creation of the world unfolds in a way in which God begins to create and develop things as he sees that they are good and beautiful. The creation starts with more general and simpler things such as the creation of light. And with this light came goodness and beauty that inspired God to keep on creating things until he reached his final creation with are humans themselves. I believe this demonstrates how after God created humans there was nothing more that he could do for the Earth, and he essentially gives humans this paradisiacal land he created for us to use and care for. He hands the task of continuing the development and of populating the Earth to humans as he backs away to the seventh day of creation in which he rests.
The human person doesn’t have a major role in this account until the last part, once God says “Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea and over the birds of the air and over every living thing that moves upon the earth.” In here, God gives the human person control and dominion over the land and places humans in charge of caring for it. It is no longer God’s responsibility to keep on populating and directly ruling over the land, but rather it becomes people’s responsibility to do so. I believe that this is connected to the way in which God decides to rest on the seventh day, even though it is unnecessary for him to do so. I think that this seventh day of rest is established to convey the way in which God gives humans the responsibility and power to rule over the Earth and continue its development, as he has already created all the good and beautiful things that he can create. Also, I think this further conveys how this seventh day is a representation of a day in which humans must take a break and appreciate all the goodness that God created and be grateful and devote that day to him and to give thanks for the Earth and everything in it.
