billions of solar systems with no life in them.I understand their point though ...
Life might have evolved in that solar system.
A porpoise is good to have, having no porpoise blinds us.
Go get a porpoise and begin to sea.
Just in this galaxy alone and many with no viable planets.
But yes might work out better after the rock falls and only sea life survives.
a few hundred thousand years later this might be a nice place with a peaceful dominant species?
