When god created everything, the light was shining on darkness and the "darkness" never mastered it. The tree of knowledge of good and evil was also there when god created everything. The serpent acted against the will of God and which is supposed to be a lesser creation than the humans as envisaged by God.
How come God allowed a serpent cheat humans which God created in His own image and likeness?
Could there be a force against the will of God?
