No. Hawking's scientific work is on the record and it concerns theoretical physics. The comments he made in the article were personal beliefs about his atheism and why he thinks science offers a better answer to creation of the universe than religious miracles. He is entitled to his beliefs, too. Nobody disputes that. The counterpoint is that none of them can prove their religious beliefs thorough science. People are entitled to believe whatever they wish, their status as a scientist offers no scientific validation of their personal beliefs. Neither Plank nor Hawking.
