The whole point is that there are unanswered questions.  We can subscribe to theoretical physics, Norse mythology, or the Church of the Flying Spaghetti Monster to try to answer the unanswerable.  None of them is really more valid than any of the others.  We won't ever know for sure how the universe was created or what happens when we die, and we have been struggling with those questions since we were first capable of abstract thought.

If a certain belief gives you comfort, who is anyone to argue?

The only failing in any faith is intolerance of another.
