How did beer get invented?

i know, who really cares, just as long as it’s cold and there’s plenty of it. but what is it about this beverage we enjoy that got figured out before we were born? i mean, who knew?

why are you a beer drinker? i ain’t talking about root beer. i mean, what compels you to snap it open as soon as you get home from a hard day’s work. how did this taste become acquired? why? how did the inventors know we’d want it?
