@fmf saidI used to think like that, but then you realise with the same logic you cannot say
He categorically stated that "there is no God" which is not something I can do or that I can agree with him about. In fact, I am sure most here would agree with me on this issue.
Despite his education, expertise and knowledge ~ not to mention his field of research ~ surely he is no more or less able to speculate accurately about the existence of a god or gods - or "God", if you prefer - than any of us here, right?
"there are no unicorns" or "there is no FSM" because we can never know what does not exist.
So for all practicality I prefer to say "There are no unicorns, there are no gods" while
still acknowledging that on some far distant planet there may be horses with horns.
