> the water was dirty This is made up. Most people had access to clean water, and water that we might today consider dirty, they didn't. (municipal water today is often "dirtier" than some fresh water sources were back then. even today, when natural habitats are restored to their pristine forms, many rivers and streams become clean enough to drink from) > beer was healthier because boiling the water was part of the brewing process and being beer meant it stayed clean for a while I'll grant you they knew that boiling water made it healthier, but if they just needed to drink a healthier version of their water source they could have drank boiled water. They drank beer because beer is tasty (and because it was basically liquid bread) > whereas just boiled water reverts to being unclean pretty quickly This is made up. Boiled water put into a clean vessel with a lid stays clean. Anybody with a kettle (any person for 3,000+ yrs...) can tell you that. Until the 19th/20th century, nobody thought this way about water or beer. All of these things were made up after people finally realized that water could have pathogens. The whole idea is an anachronism.
