Have you actually seen it, or is this just trolling? They make outlandish claims. Things like it invented society. Sure, maybe growing grain was one reason, but unless they were there to see it then it's a theory. Also, it's really hard to say that one single factor let to a complex system. You don't have to be a historian to know that there are many factors that cause shifts in society. I have heard the same said about bread. In fact bread and beer at the time of society forming were almost indistinguishable. It's very muddy water and this program is one VERY extreme view of what could have happened, and I'm pretty sure it was meant to be a little humorous in its outlandish claims. You should really watch it.
