the discovery of coffee

How in the world did people discover how to make coffee out of coffee beans? Someone must have accidentally threw some beans in a fire, and then found them later and, just for fun, ground the roasted beans with some rocks. After that, they must have said, this bean powder looks so dry, lets add it to some boiling water to make it less dry. And then they must have smelled the weird coffee smell and one of them dared another one to drink the black boiling potion. He must have felt very hyper afterwards and run around jabbering about stuff, and so everyone thought they were magic beans. That’s probably how coffee was invented.
