Purpose

What is the purpose of life? Well, I am an atheist so I do not believe in the Christian conception that human existence is simply for the glory of God,  nor do I accept the belief that people live as to worship god. I do, however, accept the Buddhist belief that people live as to suffering. It is very similar to Darwinism, people live as to survive. In fact, I see that there is, in fact, no designated purpose in living. Humans come into existence as for the sake of existence. Like arts for arts sake, humans live for the sake of something that fills up space. It is just like asking some; "what is the purpose of the ozone layer?", foolish people will answer that they were made as a shield against ultraviolet radiation and sustain life forms on earth. But is that true? Does the ozone layer assign itself the mission to protect humans, animals, plants? Not really. It is simply a natural phenomenon that conveniently has the function of shielding humans from the radiation. In this sense, we exist as a natural phenomenon. Maybe because the universe has way too many atoms and decides to spare us some. However, people are unlike the ozone layer. We can think for ourselves. We can make our own purpose in living. One common purpose of living which is well respected would be people's pursuit for knowledge or eternal truth. Note that in a way, their purpose is to discover the purpose of their existence. One should clearly see the futility in it already.
