The Book of Genesis opens the Hebrew Bible with the story of creation. God, a spirit hovering over an empty, watery void, creates the world by speaking into the darkness and calling into being light, sky, land, vegetation, and living creatures over the course of six days. Each day, he pauses to pronounce his works "good" (1:4). On the sixth day, God declares his intention to make a being in his "own image," and he creates humankind (1:26). He fashions a man out of dust and forms a woman out of the man's rib. God places the two people, Adam and Eve, in the idyllic garden of Eden, encouraging them to procreate and to enjoy the created world fully, and forbidding them to eat from the tree of the knowledge of good and evil.
