Answer 1

There’s the theory that someone wanted sweet water. So they put honey and water into a jar mixed it, took a few sips, closed the lid and put the stuff away for a few days / weeks. Then opened it again and drank from it again, unknowingly being the first person to drink alcohol. And mead at that.

Then they wanted more of the stuff, so they repeated the process. And then they experimented.
