How do we know that Eve is the mother of all living according to the Bible?

Eve is referred to as the 'mother of all living' in Genesis 3:20, which establishes her as the progenitor of the human race. This title signifies not only her biological role in bearing children but also emphasizes the theological truth that all humanity descends from this first couple created by God. Theologically, this connects to the concept of original sin, where through Adam and Eve, all of humanity inherits a sinful nature. Thus, Eve’s role is foundational not only in physical lineage but also in the spiritual narrative of humanity's need for redemption through Christ, represented as the second Adam.
