Based on this definition there is a scientifically recognized even that without question has to be a supernatural event. The prime evidence for this event it the fact you exist to read this article. The supernatural event I am referring to is the beginning of Universe. The fact that the universe had a beginning is a well established scientific fact.
Now regardless of how the Universe actually began it had to be started from outside itself. This is evident from the fact that until the universe existed there was no inside the universe and so the cause that started the universe had to be out side of it.
The fore the beginning of the Universe by definition has to be a supernatural event.
