Hey, UK contains ALL religions. So, those who don't believe in God, would have to include at least atheists, non-believers of any kind, buddhists, taoists etc. And if they REALLY want to break the b.. even the muslims. They DO have the same god but jsut call it different.
A buddhist, taoists, etc, no matter how "believers" they are (how far they follow their path) just don't have a / the god.
I find the whole article (I saw something in BBC website about it) written by a christian who felt worried thtat there are so many otehr ways of living than his/hers.
Peace,
