The Garden of Eden

...At some point something must have come from nothing...

In this chapter, the debate of "something from nothing" and "always existing" occurs. Who Sophie is, is brought up in this chapter, and a bit about her life. It all begins when she opens her mailbox, and there's a letter asking "Who are you?". Then another asking "Where did the world come from?". Then she argues with herself about the topic a little, and the chapter ends.
