Are you really comfortable with that, and does it mean it is thereby not possible for life to exist, emerge or evolve elsewhere [different conditions], or do you mean, other reasonably similar to earth conditions would surely result in life?
I mean you're not going to get a zebra on Pluto because Pluto is nothing like Earth. If there is life on Pluto it is very very very very very very different from life here. Pluto has a very thin atmosphere (during the parts of its orbit when it has an atmosphere) of nitrogen, methane and carbon dioxide. It has a surface temp of around 44K. Zebras can't live under these condition. I would imagine that the vast majority of transitional species between your hypothetical virus and the zebra couln't live in these conditions.
If the conditions are not right in Pluto, can they see that in another galaxy the right conditions prevail, and would they mirgrate there, as do birds and animals here?
This is nonsense. All i'm trying to point out to you is that because of the extreme differences in enviroment between Earth and Pluto, you're not going to have the same organisms evolve. It has nothing to do with evolution only working on Earth.

If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist!
