OK.
So initially, the Bible was a historical mythology based upon a traditional GOD idea, relative to a few semi-desert dwelling Middle Eastern folk, who existed a few thousand years ago.
Then a few thousand years later a broader regional chapter was added to the collection of folk tales and fantasy, based upon the activities of a new central character with magical powers, who was supposedly the son of himself....Mythology indeed.
So the Romans et el loosely based popular religions and political ideologies upon said mythology...Often brutally.
So generational data transfer, and the fallible nature of the human brain is what it is, and therefore global society has become what it has become.
Though Universally, I doubt that the influence of Roman Catholicism extends much beyond the Space Station.
Nonetheless, if a similarly evolved intellectual species exists in the Xtrollian sector on the Planet W'hey, they will probably have come up with similar ideas in a similar fashion.
Though I fancy that the W'heyians whistle like Marmots, and the whistle for GOD is what we would refer to as a wolf whistle... So if they turn up and start whistling at you, don't be offended, they will just think that you smell like a goddess.
