This chapter took place before records were being made so it is called pre-history. Also, it doesn’t specifically tell us how long they lived in the Garden of Eden.
This chapter continues to discuss, God, Adam & Eve. This is the introduction of the serpent who is described as a deceiver.
Verses 1-7: The serpent came to Eve and asked her what rules God made about the trees. Eve explained which tree and what would happen. The serpent deceived her by telling her that wasn’t true at all but instead eating the fruit would make them more like God. Eve ate the fruit and then gave some to her husband. Immediately they felt shame for being naked.
