Divine Inspiration

[Fake Messiah]

No ones religious, because they’re looking to acquire some quasi-scientific fact, but for something to live for.

In my religious view, the answer is something greater than oneself, a sacrificial love, that’s transformative and redemptive, and tragic in our world.

So if someone believes that Earth is 6000 years old he is believing in it because it is something he lives for? It fulfills his life? But the problem is that  it would be far more productive for society to devote yourself (or as you say "sacrifice") to science because that would be beneficiary to humanity.

Someone could find fulfilling believing that Sleeping Beauty is real, especially if he lives near the woods. So he goes every day looking for house where Sleeping Beauty sleeps in the woods. He can't ever find her, but to him this is even more encouraging because he explains himself it is because the evil fairy is making him wander in woods in circles, distracting him so it is invigorating him even more to look for her (it proves there is magic). Sometimes he even finds chunks of wood for which he believes are parts of the Spinning Wheel and that excites him even more and he lives for his expeditions into the woods.
But it would be far more useful for society if this guy lived in reality, maybe even took up science and invented some new batteries or became a doctor... So his beliefs are counterproductive.

Unless he is mentally restrained so it is better for society he believes in Sleeping Beauty than roaming on streets, harming himself or even doing some crime.
