Do you think that part of the reason why so many people believe in a God is that they just are not savvy when it comes to astronomy? It seems that the majority of people are woefully deficient when it comes to understanding the cosmos. If they really understood how big... how really ENORMOUS the universe is, and how many stars, planets, and other objects there are, perhaps they would find it more difficult to posit that a being could have been the prime cause of it all.
I think that most people have the "Star Trek" mentality in regards to the universe. In other words, they have this notion (due in large part to TV) that it is, if not easy, then certainly "feasible" to zip across the cosmos from planet to planet and star to star (assuming a technology only slightly more advanced than our space shuttle). They are not familiar with the numbers, distances, timescales, forces, sizes, and physics that govern our universe. In fact, they don't give cosmology much thought at all. They live in the confines of the here and now. To them, a picture taken by Hubble is, well... just a picture. They fail to see the story that the picture tells. The story that light has travelled for millions or billions of years before being captured by Hubble's lens. That it would literally take thousands, or millions, of earths to fill up the volume of most stars. That we are just a Gamma Ray Burst away from extinction. To them, the universe is merely "big." To them it's a "quaint" universe. It's static. It's traversable. It's benign. And it's here for us.
I realize that some may take the very points I have made as even more proof that there is a God. But... do they REALLY understand the cosmology involved? I can say that from my own personal experience the religious faithful that I interact with do not have even a 5th grade understanding of astronomy. That's not to say they are not savvy (or even exceptional) in other areas. But they certainly do not grasp (or are not aware of) the concepts I have made. And I often wonder if their religious views would be changed if they had a better understanding of Astronomy.
