Beer was never invented. It was discovered, like fire or water.
The most widely held belief, is that it was found in nature, as the very process is natural. Although recipes and conditions are fairly strict for quality control, making beer is one of the simplest things to make.
You only need water, grains of most any sort (germinated), and yeast, which is in nature.
One version of the story is that someone happened upon a puddle or pool of water that had grains in it (think puddle in a field), and yeast had somehow blown in, producing the alcohol.
It's also believed that beer is the cause of nomads settling down, so they could grow the grains required for the production of beer.
The discovery of beer has been linked to the Neolithic Revolution because the cultivation of grains for brewing may have contributed to the development of agriculture and settled societies. The production of beer could have also played a role in fostering social gatherings and community cohesion among early agricultural societies.
