^^^Exactly. Science is a process, a way of doing things systematically and carefully.
People do things scientifically all the time, even though they are not scientists. Whether it is tinkering with a pie crust recipe, or tinkering with a car engine--the solution will be a real world one, not a supernatural one. That is true no matter what the person "believes".
Anytime someone approaches a problem, thinks of a solution, tries it out and then adds what they found out to their knowledge, they are using aspects of the scientific method.
