In days gone by when the average guy on the street was not very well educated it was trivial for authoritarian religious organizations to declare themselves as the sole source of information about anything related to cosmology or any other branch of science.
Heretics who dared challenge religious conventions over matters of fact were simply put to death, or otherwise silenced. The priests had all the answers and you were required to agree.
Then came science and the education of the masses. As people learned explanations of our world that were not only rational but also demonstrably true, the more primitive notions of religions are either exposed as false or deprecated as no longer required, since a more logical explanation is now available.
Even in Ireland the number of people afflicted with religious delusions is going down. Worldwide ancient religions are in decline.
Science does have a better explanation, and if bits of what we believe today are found not to be true science will gladly accept a more accurate way of perceiving the reality that waits patiently to be discovered.
The arc of history does bend toward justice, especially as we improve our ability to understand the reality in which we all exist.
It's all good.
