When Adam and Eve sinned, God's entire earthly creation which was once perfect became tarnished, rebellious and sinful. All the sin, sorrows and sufferings we see in the world today was a result of Adam and Eve's sin. But God could have saved Himself the trouble by destroying Adam and Eve right from the beginning and He could have created a better breed of beings. Why would a loving God allow sin to creep into the world knowing well that it would affect billions of people later? God knew Jesus would have to die, so why even let His son die on the cross when He could have "taken care" of the whole situation from Genesis by destroying Adam and creating a new breed of beings?
