The Book of Genesis is the first book of the Bible. It was originally written in Hebrew by Moses around 1450 BC. Genesis answers the question "Where did I come from?" and describes God's creation of the heavens, earth, plants, animals, and mankind. It tells of Adam and Eve's sin in the Garden of Eden and the spread of sin through their descendants, leading God to flood the earth. After the flood, God scattered the nations through confusing their languages at the Tower of Babel. The book follows the lineage of Abraham and his descendants Isaac and Jacob, and tells the story of Joseph's journey from being sold into slavery in Egypt to becoming a powerful ruler in Egypt who saved his family during a famine.
