What is the meaning of life?
The most accurate answer to that question is: "Whatever you think is meaningful in your life, e.g. your education, work, family etc." But being human, that is not the answer you are looking for: You want your life to be meaningful from an objective point of view, "as part of a greater whole". Sadly, that is not the case: From the perspective of the universe your life is completely futile and negligible.
Perhaps you consider yourself a humanitarian or breaker of new ground in one way or another, but what is (from an outside perspective) meaningful about that? The people you may influence will be long gone and you and your achievements completely ineffective in some hundred years from now, a negligible timespan in relation to the universe.
Referring to God or some higher power is just a way of putting off the question, since you then owe us an explanation of what the meaning of God (or that higher power) is. But by being a higher power, it follows that you are unable to comprehend it, wherefore we are led to conclude that believing in God is just another way of believing that the universe is meaningful, but not to us. And that is hardly an answer to the original question.
Following Wittgenstein we could take another approach and consider the question itself meaningless. This is because "meaning of x" is a statement in life conveying something about the consequences of x, the significance of x etc. So when "x" is replaced by "life" in the statement "meaning of x", the statement becomes recursive and therefore nonsensical.
As far as FAQTA is concerned, the real philosophical issue here is what conclusions we draw from the realization of life's meninglessness. FAQTA encourages you to read "The myth of Sisyphus" by Albert Camus and come back with a more daring question.
