I'm a financial analyst for a Brewery. They company makes and sells fine beer.
Oh really? I like a good beer as long as its on tap or bottled
Have you ever visited a place where they make beer commercially? Like a brewery or beerhouse? 
No but id love to go one day.
This guy who owns the place told me that commercial brewing has been going on since 2500 BC, in Mesopotamia. 
Wow commercial brewing? thats insane.
I know, I was surprised too. It's one of the oldest beverages ever produced. It's production was recorded in Iran and Egypt as well.
I dont even know how they discovered beer that long ago.
I guess maybe they found out that basically any cereals that contain sugars undergo fermentation eventually. There are also wild yeasts that exist so fermentation can occur naturally. 
Huh mustve been weird getting drunk for the first time haha
