That’s not an argument. Saying that a thing will die if it doesn’t act towards the preservation of it’s being is just an observation. That doesn’t change the fact that there are physical beings that are in fact acting for the preservation of their existence. That makes sense if an intelligent being intended physical nature to behave that way, because the preservation of “life” as a concept is an intelligent end not a physical end… But given the fact physical processes are fundamentally blind to that end, if there is no intelligent cause, then the existence of such activity makes no intelligible sense.
