It's very simple: that fictional character you call "I"? Once the illusory self is self-created, it must necessarily include an 'other', and that 'other' is the idea of 'God', which is only a projection of the self. So, to extrapolate a bit further on YOUR position, that the word 'God' is ONLY a word, it is more than just a word, as it conjures up images thought to be real which are then acted upon. This is the God of which belief is the target. It is the realm of the orthodox believer.
Having said that, what lies beyond concept and belief is what is real, and can only be accessed via of the non-conceptual, intuitive mind. This is the realm of the mystic.
Even the atheist is attached to the idea of God, and has not gone beyond the world of conceptual thought to direct spiritual experience.
The believer and the atheist/sceptic are two peas in a pod. In order to get anywhere, they must get out of the trap of dualism first.

Neti, Neti
Not this, not this (Neti, Neti); for there is no other and more appropriate description (of Brahman) than this Not this....
We can never truly define God in words. All we can say, in effect, is that "It isn't this, but also, it isn't that either". In the end, the student must transcend words to understand the nature of the Divine. In this sense, neti-neti is not a denial. Rather, it is an assertion that whatever the Divine may be, when we attempt to capture it in human words, we must inevitably fall short, because we are limited in understanding, and words are limited in ability to express the transcendent.
