That was another thing I was thinking about.
Change is the normal state (well actually statelessness) of the world. And the job of life (now I mean the abstract entity) is to adapt according to the new situation, to transform shape and behaviour along the change. Catastrophic events - like that asteroid hits - which caused extinction waves are part of the change. The extinction came from the inability of a certain species to adapt, and their disappearance pulled many other species into oblivion relying on their existence. So life itself (as an abstract entity) wasn't in danger, but certain forms of life.
