@roammer,
The point about the etymology of words is that they signify historically shifting
concepts or nodes of communicative agreement regarding
human functioning. For example the meaning "thing" can be (roughly) traced from its connection with" a public assembly" (old Norse), through "focal matter" to "existent item". But this implies an argument that "existence" itself presupposes "human interest", hence "the existence of God" may be merely a concern of human psychology rather than anything to do with an independent entity. Similar etymological arguments concern the verb "make" (
facere in Latin) which is the origin of the word "fact", implying that "facts" are cognitive constructions.
From this you should be able to see why questions about "belief in God" are considered to be either philosophically trivial, or outside the remit of ordinary discourse because the word "God" implies no
agreed communicative function for humans.
