The word 'good' is used 7 times to describe God's creation in Genesis Chapter 1. The final use is coupled with "very," as in "very good," when God describes man. The Hebrew word for good is 'towb' as opposed to 'tamiym,' or perfect (see Gen 6:9 when God calls Noah perfect in his generation or Lev. 22:21 as it relates to the type of sacrifice required by God).
Not only does God limit His description of the Earth to good, but He tells Adam and Eve to subdue it (the Hebrew word kabash) in Gen. 1:28. Furthermore, in Gen. 3:16 God tells Eve, as a punishment for eating of the tree, that he will multiply her pain in childbirth. I was not a math major, but anything multiplied by zero, is still zero. So childbirth prior to the fall must have still hurt for the pain to be multiplied. Then there is that little thing about the serpent roaming around...
I had often thought of Earth prior to the sin of Adam and Eve as a perfect and spotless paradise. It is not that God couldn't have made it perfect, but I am not so sure that God intended it to be so at that point in time.
