Why does the Bible say Adam and Eve were the first humans? The Bible clearly states Cain was sent to a land called Nod. If there was no people there, then why was he afraid someone would hurt him?

The story of Adam and Eve in the Bible is often interpreted as the origin of humanity, but it's important to note that it is a religious narrative rather than a historical or scientific account. The concept of Adam and Eve as the first humans is a theological interpretation within the context of the Abrahamic religions (Judaism, Christianity, and Islam).

Regarding Cain's fear of being harmed after being sent to the land of Nod, according to the Bible, Cain was expelled from his family after he murdered his brother Abel. The land of Nod is described as east of Eden, where Cain settled after being marked by God. The Bible doesn't explicitly state that there were no other people in the land of Nod; rather, it focuses on Cain's fear of being avenged for his crime.

Some interpretations suggest that there were other people outside the immediate family of Adam and Eve, which could explain Cain's concern about encountering others. However, the text itself doesn't provide explicit details about the population of the land of Nod or the origin of other people outside of Adam and Eve's family.

It's important to approach religious texts with an understanding of their historical and cultural contexts, as well as acknowledging the diversity of interpretations within different religious traditions.
