What is so "fairy tale" about being taught and encouraged to be a good person. The idea that religion has lost its relevance to you based on that is I think terribly discomfiting if not totally disappointing.
There are areas of concordance between science and religion. Science deals with the material and physical, but religion elucidates on that material aspect of life with the concept that man must assume and aim most importantly for the spiritual. Now if you don't believe that a supernatural world exist, then I suppose you can go your own merry way.
