Original sin, also described as ancestral sin, is a Christian view of the nature of sin in which humanity has existed since the fall of man. Original sin arose from Adam and Eve's transgression in Eden, the sin of disobedience in eating the forbidden fruit from the tree of the knowledge of good and evil. Original sin can be explained as “that sin and its guilt that we all possess in God’s eyes as a direct result of Adam’s sin in the Garden of Eden.”
