Maybe, as Shaun says, the meaning of life is not defined by anything other than ourselves -- but perhaps it's a human being's exercise of volition that makes our purpose in life valid? We are given the ability to think, the capacity to gain knowledge and learn and the capability of making decisions, after all -- maybe all of these are tools in aiding us to find out the meaning of our life.

I won't say either that everyone has the same meaning in life; I think it differs from person to person, so while death is the end we all achieve (like Shaun says), the way we live our life will give it more meaning than the end result.
