If religion were true, its followers would not try to bludgeon their young into an artificial conformity; but would merely insist on their unbending quest for truth, irrespective of artificial backgrounds or practical consequences.
One may say with one's lips: “I believe that the world was created six thousand years ago;” or, “I believe that Jesus flew away into the skies and is sitting on the right hand of the Father;” or, “God is One, and also Three;” — but no one can believe it, because the words have no sense.
The first and last lesson of religion is, "The things that are seen, are temporal; the things that are unseen, are eternal." It puts an affront upon nature.
