Coffee was discovered by an Ethiopian goat herd called Kaldi in the 1500s. He saw his goat eating coffee cherries and later observed a change in their behavior- gained high amount of energy and they didn't sleep at night.
Kaldi shared his findings with local monks and then after they made a drink with coffee beans, they realized they could stay up all night and pray. They spread the experience and it reached across the world.
