Is there a meaning to life?
Answer: if there is no meaning to life, then the question "Is there meaning?" can have no meaning.
If the question does have meaning, however, then clearly, there is meaning to life, since there is meaning in the question, "Is there meaning?"
The answer is in the question: it is that the question "Is there a meaning to life?" is either meaningless, or it answers itself.
In either case, the question is 100% redundant.
