I believe in miracles, but if I were a scientist I would have to assume no miracles, then proceed. It is the sensible working principle.
Of course, as a person (which is a bigger category than the category “scientist”), the assumption no miracles is a philosophical position, not just a working principle. The first is begging the question, the second is a methodology.
It just seems to me that many of our creationists want scientists to somehow include God in their studies (as if.), and many scientists talk as if their scientific work is the sum of their personal interaction with the universe.
Impoverished on both sides.
