Original sin
Original sin, also called ancestral sin, is a Christian belief in a state of sin in which humanity has existed since the fall of man, stemming from Adam and Eve's rebellion in the Garden of Eden, namely the sin of disobedience in consuming the forbidden fruit from the tree of the knowledge of good and evil. Theologians have characterized this condition in many ways, seeing it as ranging from something as insignificant as a slight deficiency, or a tendency toward sin yet without collective guilt, referred to as a "sin nature", to something as drastic as total depravity or automatic guilt of all humans through collective guilt.
