Yes it’s not too hard: Make a hole in a garden hose and it will never stop letting water out. Make a hole in human skin and blood will come out, for a while, then a miracle occurs and slowly the bleeding stops.
You did nothing. Unseen, a small army of ‘friendly blood cells’ go to work to stop the bleeding. A miracle? Yes!
People in Jesus day asked this same question you have asked. Jesus said “The only miracle you will see will be like Jonah in the whale. I will be in the earth three days and three nights.”(Mt.12:38-42). Jesus was talking about his resurrection after His death.
Crusty old atheists are smart when they look at a new born baby and say: “Beautiful – it’s a miracle.”
Joke: A child was busily drawing in Sunday School and the teacher asked: “What are you drawing?” “I am drawing God.” “But nobody knows what God looks like.” “Well, they will when I’m finished,” says the child.
