[Fallout] Does the average person living in the wasteland know that the world ended?

Do they know about the Great War in 2077 or anything about the old world? I know the Vaults would pass down some of that info, but I mean there are people today who know nothing about what the world was like 200 years ago.

The average wastelander probably know of the Great War as they live in the results of that war, but likely nothing beyond that nor would they care.  You do have folks who are interested in the past for various reasons:  Abraham Washington in Rivet City for example.  But sometimes these amateur historians tend to get things wrong.  Baseball wasn't a blood sport, Moe.

And there are also ghouls that were alive prior to the War and may pass on pre-war knowledge to anyone who would listen.  It is also possible that salvagers and prospectors would glean information from still working terminals in the buildings that they were looting.

The various factions and organizations (Brotherhood of Steel, the Enclave, the Institute, the NCR) likely have the most accurate historical records but shape the narrative to fit their own agendas.
