How about this for the meaning of life?

The meaning of life? The ultimate question in human evolution. Well heres your answer, there isn't one. There is no meaning of life. Everyone always says our meaning of life but what about the meaning of life to a tree. Some would say they produce oxygen from carbon dioxide, enabling us to live, ero giving them a purpose, but what about that tree's actually meaning of life? Just because we are at the top of the evolution chain doesn't mean we are the only thing to exist on this planet. Every animal and material on this planet serves us in one way or another, wether for survival or develpment, but who do we serve? Thats the reality behind the question of our "Meaning of Life ". We serve one-another, so our meaning of life? To enable the survival of our race at the top of the chain. This is the purpose of the dominant species, to adapt to help each other to survive. Probably could have found this question and answered it but hey ho! Thoughts?
