How Unique is Earth?
28 New Exoplanets Discovered tells us about the continual addition of new planets to an ever growing list of extra-solar planets. We know enough already to appreciate the uniqueness of earth in our universe. It is difficult even to locate planets with conditions that would allow for life. Yet it is planets which could be hospitable to life that are the most intriguing. If life arose on earth, why would it not do the same everywhere in the universe where conditions reasonably approximate those on prebiotic earth?
A designer centered cosmological outlook could explain earth's unique status and make predictions as to the likehood of finding life elsewhere in the universe. A non-designer outlook is pegged to environmental factors. Here is the opening paragraph at the linked website:
"Astronomers have discovered 28 new planets outside of our solar system, increasing to 236 the number of known exoplanets, revealing that planets can exist around a broad spectrum of stellar types-from tiny, dim stars to giants."
