Man was given authority
28 God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground.”
God gave Man authority over the whole earth and all that was in it. After the blessing God gave authority. As proof of Man’s dominion over the Earth, God brought the animals to Adam to name them.
19 Now the Lord God had formed out of the ground all the beasts of the field and all the birds of the air. He brought them to the man to see what he would name them; and whatever the man called each living creature, that was its name. 20 So the man gave names to all the livestock, the birds of the air and all the beasts of the field.
Mankind was created not just to have dominion over the Earth and all that was in it. He was also created to have close, intimate fellowship with God. Adam and Eve were so close to God, they even knew the sound of his walk.
