I think that the meaning of life is much more deeper than to be discussed here and as easily.
If we think of it for centuries we wont be able to find the answer at all, for ir is known only to those who should.
I personaly believe that every person in this world have a reason to live for. A dream or something. As of why we were created in the first place? this question is as complicated as of thinking what might lie behind our galaxy and how far space goes.
Life is complicated as it is without questioning the porpuse of it.
