I want to know the answer to the following question:
What theory claims that popular belief was based on fiction?
All the background I'm provided with is that "For Varro - well versed in Euhemerus' theory - popular religious observance was based on a necessary fiction; what the people believed was not itself the truth, but their observance led them to as much higher truth as their limited capacity could deal with.". Is that enough to answer the question?
