I know what kind of scientist the above poster is. They are a marketing psychologist. I don't think that makes them any more qualified to say whether or not any of the other scientists have established any evidence that there is no god, or even that the question is closed and doesn't require any further study. In fact, I would be willing to bet money that they don't have any evidence whatever that any branch of science has determined that there is no reason to keep the question open any longer.
