I propose that Genesis 1:1 represents an example of introductory encapsulation, providing a summary of all the events of the Creation Week. The creative acts described in the account of Day Two (Genesis 1:6–8) thus refer to the astronomical heaven. This establishes a foundation for building a biblical model of astronomy. This approach also makes three bold statements about the universe. As an added benefit, it may provide a simple explanation for the CMB (cosmic microwave background).
