Science and its methods cannot answer all questions.
On the one hand, there are certain areas which cannot be answered by scientific methods. This does not mean that scientists do not have an opinion with respect to these questions. However, their opinions are those of human beings and not scientific ones. Moreover, there are also questions to which science has not found an answer so far, and it can be questioned whether science will ever find an answer.
Stories where this aspect plays an important role are:
