You know, in other Universes, there could be completely different types of life, but they aren't found here because conditions aren't right?

I think the Universe, by virtue of it's huge extent in time, space, mass, and particle number is inherently predisposed to allow SOME sort of complexity to develop. The one we're in, we call "Life". there may be others, frantically evolving in the plasma cores of stars, for example...

Don't be so anthropocentric to imagine that our sort of life is the "only possible" one. It's merely the only one we see in our region of time, space, and probability!
