@Owen phil,
Sorry, but the phrase "analytical twaddle" comes to mind !
As an atheist I assert that the
concept "God" exists, because I am discussing it. I further assert that
all we have are concepts and that includes everything from "rocks" to "dark matter". What marks me out as "an atheist" is the
functionality (semantic inter-relationships) of "the God concept" with respect to "me" (another
concept) as opposed to its functionality to "a believer". i.e. For "me", it does not function as creative or comforting concept, has no tangible physical manifestations, and is neutral with respect to manifestations of what "I" might call "good" or "evil".
