Final answer:
Adam and Eve lived in Eden, also known as Paradise, where they had access to the tree of life and the tree of the knowledge of good and evil, until their disobedience caused their expulsion.
Step-by-step explanation:
Before the Fall, Adam and Eve lived in Eden, which is often termed Paradise. In the biblical account of Genesis, Eden is described as a garden planted by the LORD God, complete with beautiful and fruitful trees, including two notable ones: the tree of life and the tree of the knowledge of good and evil. The Book of Genesis tells a story where Adam and Eve, the first humans, lived in Eden until they disobeyed God by eating from the tree of the knowledge of good and evil, leading to their expulsion from the garden and access to the eternal life provided by the tree of life was subsequently denied.
