The "Fall of Man" refers to the biblical event in which the first humans, Adam and Eve, disobeyed God by eating the forbidden fruit from the Tree of Knowledge in the Garden of Eden. This act of disobedience is often seen as the moment sin entered the world, leading to their expulsion from the garden and a change in the relationship between humanity and God. This event is significant in Judeo-Christian theology as it explains the origin of human suffering and the need for redemption. The consequences of the Fall include mortality, labor, and a tendency toward sin, shaping the narrative of humanity's struggle and the promise of salvation through figures like Jesus Christ.
