Science

fromcomet tails to interstellar dust and gas. Having us be alone in the immensity of even the small part of the universe we can percive beggars the imagination.

The problem is that any life not evolving on Earth would most likely be unrecognizable to us as such, not even if it tapped us on the shoulder and said its equivalent of "howdy."

Will we ever know for sure? Not unless there's something recognizable on other planets or moons in our own system. We have a ghost of a chance of seeing it as alive.

My guess still says it's all alive. Nothing else makes a lot of sense.
