Meaning of Life
Pretend for a second that life doesn't have a meaning. That from birth, you are born into a world, an environment, that has no purpose. If you were to assign a meaning to life at this point, it would simply be to exist. And you could probably live off of that for a good 12 years or so. But around that time, you need something more fulfilling. Life just isn't as simple anymore.
You start searching. Some people find that religion gives them a purpose; a goal above all else that is, generally, to be good and in turn have a happy afterlife. Some people have been brought up to already "know" what their purpose is, such as becoming a football star or keeping up the family tradition of being train conductors. Then, seemingly the biggest group of people, assimilate into the ones around them who haven't found a thing, or might not even know they should/could be looking for one. And these people may handle it differently, whether it's drugs or dressing in black and finding solace in themselves and others who feel the same way. The point is that many people handle this differently but share a common cause: the search for a purpose. This would seem to support the idea that there is no "meaning" or purpose to life and that, in fact, it has to be discovered.
And I think that's what life is all about. We as humans need a purpose to keep us motivated to survive in this world, and although there might not be a purpose from birth, with the right knowledge you can make your purpose and, in turn, give your life a meaning.
