Earth's particular location gives humans a special window to the solar system

Earth's particular location gives humans a special window to the solar system, the Milky Way galaxy, and the universe itself. In virtually any other galaxy or at any other location in Earth's galaxy and at every other time in cosmic history, the view to the surrounding area would be so unstable and/or so occluded that the form, structure, size, and other characteristics of the galaxy and universe would remain obscure to any sentient observers.10 Earth's creatures enjoy a special view to the splendors of the cosmos. Nowhere else and at no other time in the universe would such glory be visible.11

Why is it important that we are not in one of the spiral arms? First, our location gives us a view of the universe that is unobstructed by the debris and gases found in the spiral arms. This fact allows us to visualize what the Bible says, "The heavens declare the glory of God." If we were within the spiral arms, our view would be significantly impaired.
