The last few years have dramatically changed the notion that life on Earth is unique. With a sample of one, there is way way to be sure, but each new discovery points in the same direction.
I would hazard a guess that the universe is indeed teeming with life, as a natural, emergent phenomenon.
That seems like a wonderful, awe inspiring thought, and yet we are still arguing as to how life evolved on our own planet. Arguing about evolution itself.
There are those who would have the universe be billions of times smaller, thousands of times younger, and with no diversity. Is that more wonderful, more spiritual?
