The ancient Roman and Greek societies and their associated religious figures and followings are reasonably well known, and, due to their classical historical significance, are continually referenced by modern society for example in the names of calendar months, planets and the Olympic Games.

However, the use of the word mythology now used in relation to those ancient religions indicates that at some point in time they ceased to be viewed as religions and were widely reclassified and accepted as nothing more than fictional fabrications.

What caused the transformation from religion to myth to occur?

For example was science the culprit, did someone wake up one day and think to themselves: 'are you 100&#37 sure about these monsters with a hundred hands and fifty heads, I have never seen one?!!'; or were the gigantic monstrosities killed by Christianity just like when David used his sling to fell Goliath?
