This argument is the last refuge for intellectuals who still believe in religion. If you ask your average church goer whether God, heaven, and hell exist and are real places they would say absolutely yes. And for them there is no equivocation, they exist the same way that a house, or car, or person does. Also, if you go back in time to before we understood things like evolution virtually everyone (with a few exceptions such as Spinoza and the American deists) believed in a physical God and actual places such as heaven and hell.
Now that science has eviscerated all the intellectual proofs for God the last defense for those who want to believe but still have a basic understanding of science is to say that for God existence means something else than for any other object. And then what follows as in this article are discussions of poetry and art and emotions. To me its obvious what is going on: people don't want to discard their comforting beliefs so they perform philosophical gymnastics that if you strip off all the flowerly language come down essentially to "God doesn't really exist but I'm going to keep on talking and behaving as if He did" Read the Article at HuffingtonPost
