You've misunderstood the purpose.
Fiction was not ever intended to achieve scientific goals, i.e. to discover the truth about our universe. It's intended to be thought-provoking, i.e. to inspire questions about our universe.
You need the question before you can find the answer.
Animal Farm entered Anglo-American classrooms in the late 1950s, and its adoption was heavily influenced by the Cold War political climate . The book was seen as "useful" for teaching, but its political utility was part of the appeal—it provided "an easy use... as an anti-Communist and anti-revolutionary lesson" . This wasn't just a grassroots phenomenon; it was actively encouraged by intelligence agencies.
Both British and American intelligence services promoted the book as an anti-socialist message and supported its distribution . The CIA even arranged for a 1954 animated film adaptation that altered Orwell's story—emphasizing that animals on neighboring farms were content and changing the ending to have the animals overthrow the pigs . This film was widely shown in US and UK classrooms, embedding a distorted version of the story in the educational system for years
I can accept the impossible for the fun of it, but when something is impossible I don't take is serious. And it wasn't a good book in general.
Which parts specifically of Animal Farm are untrue? Greed, hypocrisy, cruelty, avarice? Or the talking animals?
Old Major is Marx/Lenin, Napoleon is Stalin Snowball is Trotsky, etc. Regardless of ones nationality or politics, the story of Russia in 1917 remains one of the most fascinating in our worlds history. For a lot of people, myself included, Animal Farm served as a nice way of being introduced to the tale without getting bogged down by the specifics.
