If your rich uncle took you down the street to see a dog jump through a hoop, you might say "big whoop, but thanks anyways." But if he took you to India to see the elephants parade in front of the Taj Mahal, etc., you would say, "Wow, awesome uncle: you have really treated me special!" The bigger and more beautiful/mysterious the universe is, the better the show God has put on for us (where 'us' signifies all rational beings) Related point: To argue that considering the large size of the universe should us feel insignificant is to argue in a kind of circle, for it assumes a materialistic view of what constitutes significance/insignificance. Significance is about beauty, not about size. And if the beauty of the cosmos is for us, then we are significant indeed.
