“We absolutely must leave room for doubt or there is no progress and no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified: how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don’t know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.”
–Richard Feynman, http://en.wikiquote.org/wiki/Richard_Feynman
Maybe the answers are not satisfactory, but they are all that we have at the moment. I am primarily unconcerned with the questionable meaning of existence.
In my mind it is superior to understand the complexities of uncertainty than to wallow in an incomplete theory of being.
If you believe, then do.
