What are some examples of miracles throughout history?

When I say miracle I don’t mean in the literal supernatural sense of the word, though if you have any to share I’m open. I more mean in the sense of something miraculously and stupendously good happening whether by chance or active human effort. A eucatastrophe if you will. I can think of many times throughout history that forces or events have sort of all coincided into unilaterally terrible events that change things for the worst like 9/11 or the Holocaust, but it occurred to me I can’t think of anything similar happening in the opposite direction.
