There are some confessions that believe God is a flesh and bone human. And therefore, presumably, they would confess that the God the Creator was a man.
That however is certainly not my confession; and I am confident the majority of Judeo/Christian confessions do not hold to that interpretation either.
I believe the classic biblical understanding is that God the Creator became incarnate at a particular point in our history, and that when He did so, it was in human form. Not the form of angels or plants or animals. WRT time and space, and in view of the fact that Genesis denotes God as saying "Let us make man in our image" as the final act of creation prior to the seventh day, it is fairly certain that human attributes attend the Creator. "I AM THAT I AM" at least denotes person-hood, which in turn is largely what constitutes the human estate.
To iterate things a bit differently, it is awkward to suggest that God was entirely nonhuman at one point in time, and then changed in essence at the time He became incarnate. It is part of His essence as expressed from the beginning to become flesh and redeem His creation. Obviously it would be preposterous to understand from the biblical texts that a created human is responsible for designing and building the universe. But an uncreated being with human attributes? Not so far fetched.
Nor mine, A-G. That would seem to be the view of a very small minority.
