My view about evolution/creationism is that God may have ordered the evolution of man. He wanted the human being to became like he/she is today. That may have happened thru' evolution of species.
About The Fall
I suppose that the story of Fall to sin may not mean necessarily literally true event, but God's story to man about her/his standing in relation to Him: man does not live the life he/she could and should live and human has doubts of God, for instance.
