Everyone who is alive is creative. We create solutions to problems, we create answers to questions, we create decisions when faced with options, and on and on. No matter what title we give ourselves, we create.
So, with that in mind…
God could have created the universe all at once, in a timeless “poof!”
Genesis 1 shows God used a step-by-step process with pauses for evaluation and
time set aside to rest from creating. We can emulate His process, including the
rest. Doing so would probably be good (God) for us, who are made in His image.
