A definition, as it is normally used in modern science, must be read back to front, or from the right to the left: for it starts with the defining formula and asks for a short label to it.
Thus the scientific view of the definition "A puppy is a young dog" would be that it is an answer to the question "What shall we call a young dog?" rather than an answer to the question "What is a puppy?"
So said Karl Popper.
Some scientists seem to think that the question being posed is "What shall we call the Creator?" & their purpose just to define away the question.
Just as we can get rid of the problem of infinities by getting rid of zero.
