People were designed and created to live in complete harmony with nature. After the fall this harmony was damaged but not completely broken.
Now if we take that to a more serious level, the fall brought disharmony between the Creator and the Creation. this enmity or disharmony between God and he creation {mankind} is the state in which we were born.
People are never fully content or satisfied in their exsistence until they are brought back into harmony with God.
The Bible in the New Testament, teaches that this can only occur as a result of entering into a right relationship with Christ Jesus, Our Lord and Our Friend.
God Bless.
