  :I believe that statement refers to the fact that, for instance, a game designer can code a game without physically entering it. The laws of physics apply only to our universe, and by a few extensions to reality, and so the being which would have to originate outside of known reality in order to create it would not necessarily choose to or even be able to fully join it. I do agree that the statement only applies to a creator God that created not only Earth but reality itself, though, so I'll add that in. )
