We think of a day as 24 hours. In the account of creation, a day is defined as a period of there being light followed by night. It doesn't say how long this day was. Is it possible that the day has not always been 24 hours, that when God was creating the world the day was longer??
God said, "Let us make man in our image." Man is made in the image of the Father, Son, and Holy Spirit. What characteristics of the three do we possess? Also, how can we learn about ourselves by learning about God? By learning about God, Jesus, and the Holy Spirit, I learn what I was intended to be: to look like them. I look like them when they live in me. They live in me because I look like them. If I don't look like them, they are not living in me.
