I can see easily how they accidentally invented wine, fermented grape juice in a jar, but how in the world do you accidentally invent Beer? That is a complicated process..................
The wine reference was to the Athena from the head of Zeus thing. :^) But yeah, getting some grain wet by accident and coming back later is probably the ultimate origin of beer. Early beer was a type of gazpacho.
Also, the discovery of beer probably antedates the discovery of breadmaking, just a guess.
I believe that very little has ever been accidental.
At the risk of getting both the scientist/evolutionists AND the creationists in an uproar, I believe that the Universe is Intelligent; and Knowledge and Ideas are always floating around, so that someone with enough desire and curiosity can hook up with them...
(I think those ‘someones’ have sometimes been called ‘prophets’, ‘geniuses’, etc.)
