We humans often think of life in the universe as though it were the result of a bizarre set of accidental circumstances.   We’ve evolved enough to realize that we aren’t the center of our own solar system, let alone the universe, yet we still think of life, and most of all conscious life, as an incredible and unlikely series of events, rather than being an inevitable element of the universe, permeating it.

So when we imagine the universe, we needn’t wonder whether there are planets full of life:  Of course they are.   Millions upon millions of them.
