His biggest mistake was when he created the talking snake!
According to the bible, God created the Garden of Eden with perfection. Perfect species. Adam and Eve were supposed to live forever on earth, if and only if they obey God's commandment not to eat the fruit in the tree of knowledge.
My question is, why the hell did God created that damn tree? And attatched to that tree is a talking snake!
God was actually all knowing so the time he created the Garden of Eden, God should've known that he was about to be disobeyed by His creatures! And the talking snake would be the cause of the fall of man!
How come God didn't foresee that Adam and Eve will eat the fruit in that forbidden tree!
But, still, God's biggest mistake was when he created the talking snake!
