Final answer:
In the story of Adam and Eve from the Bible, it does not explicitly state how long they were designed to live. However, it can be inferred that they were originally designed to live forever, but because of their disobedience, they lost that privilege.
Step-by-step explanation:
In the story of Adam and Eve from the Bible, it does not explicitly state how long they were designed to live. However, after Adam and Eve ate from the forbidden tree, God banished them from the Garden of Eden and prevented them from accessing the tree of life, which would have granted them eternal life. So, it can be inferred that they were originally designed to live forever, but because of their disobedience, they lost that privilege.
