Whether one is a theistic evolutionist, a young earth creationist, or anything in between, one can still appreciate the manner in which the Genesis narrative describes God's act of creation.
God is said to have "rested" on the seventh day. As it is commonly known, the number seven represents perfection in Hebrew numerology. What is much easier to overlook is the symbolic  nature of the previous six days. Take days one and four, two and five, and three and six:
Day One: God creates light
Day Four: God creates the sun and moon
Day Two: God creates the separation between the sky and seas
Day Five: God creates birds and sea animals/fish
Day Three: God creates land and plants
Day Six: God creates animals, notably humankind
There is a parallel between the first three days and the last three. Each day there is a progression in the hierarchy of creation. The first three days describe the environment in which the latter three dwell. This is especially important for those of us who give Genesis 1:28 a "caretaker" interpretation. The earth has been created for humanity, not the other way around.  With each day what God creates is greater and greater, finally reaching its peak in humanity, having been created in God's image (Genesis 1:27). 
 For those who take a literal interpretation of the six days, I do not mean to imply "non-literal" by the use of "symbolic." Certainly something can be both literal in one sense, and symbolic in another.
 Of course, this doesn't give humanity a license to abuse the earth. Rather, we are to care for it in an analogous way to how God cares for us.
 The imago dei is a term descriptive of humankind's rationality and personhood.
