I wanted to know what the scientist believe, is the reason for human life?
even if it is not confirmed by evidence just tell me the theory.
Thnx in advance
As the some have pointed out, science doesn't address this issue. So I will use your question, if you don't mind, to reflect on something a little different (but related).
When people ask about the purpose of life, they usually just bunch together livingness and consciousness. But as Nereid seemed to suggest, an amoeba can hardly be called purposeful consciously, even if its biology is fully involved in survival. So it seems to me that to discuss a living being properly, we have to distinguish between purpose in livingness and conscious purpose.
To explain that concept a little more, the term "life" includes a huge range of organisms, from plants and bacteria to bugs and humans. When simply comparing the quality of "living" amongst life forms, it hard to say a bacterium in a pig's bowel is living less effectively than the pig with whom it's symbiotically infatuated. In fact, that intrepid intestinal invader might just be more equipped for survival than its host, and among evolutionists survival is commonly seen as the first priority of the quality of living. So if we are restricting the meaning of purpose to "livingness," then it is logical to say that that which furthers something's ability to survive can logically be labeled its
primary purpose.
But looking at life on the scale of all living organisms, there is a pattern which can be discerned in how evolution proceeded (i.e., which can't be seen within a single -- particularly early -- species):
the quality of "livingness" develops ever higher avenues for the emergence of consciousness. This fact, which is not even slightly open to doubt, could be interpreted as a
higher purpose of life (though not more "primary").
To clarify the difference between primary and higher, consider studies done on people hard at work in human society. It has been demonstrated many times that once workers' salaries are meeting survival needs, healthy human beings tend to look for ways to get creative (or
self actualize, as some put it). If survival is threatened, then survival quickly becomes the focus; but once survival is secured, mentally healthy humans look once again to creative ways to express themselves (and even NEED to in order to maintain good mental health).
If a similar hierarchy of values has prevailed in evolution, then biology’s relentless march toward organization favoring the manifestation of consciousness suggests livingness has had both a primary purpose and a higher purpose; survive first, and then to develop avenues for ever more refined/advanced emergence of consciousness.
If we at least allow such a model as a possibility, then an interesting question seems to naturally arise. What sort of forces/principles/dynamics established that hierarchy of values?
