Many things in the past were "unexplainable" and people believed them to be "miracles" until someone found a logical explanation behind it.
Just like with people getting "miraculously" better, there's probably an explanation even though to this day we cannot find one.
It's so much easier and magical for people to cast it as a "miracle" than to try to think of it as something that will probably be explained someday. It makes them feel special and blessed when it's just really an illusion.
