Inevitable life

Does the Life Have a Purpose?
No, says Christian De Duve.
"Personally, I do not accept the implications of the term “purpose.” Sticking to the facts, I prefer the undisputable statement that the universe happens to be such that certain events, including the generation of life and mind, were possible, perhaps even probable, if not obligatory. Instead of searching the “mind of God” for the explanation of this fact, I see it as an expression of reality and as a significant clue to the nature of this reality." 

"By definition, a creator must himself be uncreated, unless he is part of an endless, Russian-doll succession of creators within creators. But then, why start the succession at all? Why not have the universe itself uncreated, an actual manifestation of Ultimate Reality, rather than the work of an uncreated creator? The question is worth asking." 

Does Science See a Purpose in Life?  
Pier Luigi Luisi´s answer. 
"The main function of a living cell is thus to defend its own identity—to remain itself in the face of the many transformations which take place inside its boundary."
"...the observer scientist who looks at nature and asks the question: is there a purpose in the living nature? Is obliged to answer, in force of his/her own philosophical bias which dominate science today, that nature's purpose is self-maintenance. And nothing else."
