Let me explain the reasoning behind this bold claim. First, a certain level of entropy is essntial for life's existence. If the universe were too entropic, i.e., too efficient a radiator, stars and planets would never have formed. If it were insufficiently entropic, i.e., too inefficient a radiator, all the mass of the cosmos would have quickly collapsed into neutron stars and black holes. In correlation to the cosmic entropy level needed for life, the mass density of the universe must be fine-tuned to support the nuclear fusion that is also necessary for life.
Mass density is a catalyst for nuclear fusion.
Either way, life-essential elements such as carbon, nitrogen, oxygen, phosphorus, and potassium would be missing. The existence of even one planet like ours, a planet supporting complex creatures through whom God has chosen, expressly, to conquer evil with His triumphant love, requires the existence of ten billion trillion observable stars. He seems to have spared no expense. I see the ten billion trillion stars as a vehicle for communicating God's glory, righteousness, and love. If our position were slightly different in one direction or another, we either wouldn't exist at all or we would see nothing but nearby stars and nebulae.
