Original sin refers to the belief that all humans are born sinful because of the disobedience of Adam and Eve in the Garden of Eden. Many religions have their interpretations of original sin, including Christianity and Islam. Synonyms for the phrase include "inherited guilt," "ancestral fault," and "primordial transgression." Some might use the phrase "Fall of Man" or "Adam's curse" to describe the same concept. These synonyms highlight the idea that sin is a part of human nature inherited from our first ancestors. While the term "original sin" is predominantly associated with Christianity, the notion of inherited sin is part of a broader belief system that transcends religious boundaries.
