Objections to metaphysical arguments for the existence of God are otiose Humans' cognitive capacity co-evolved with human culture, as it is culture that allows the brain to fully realize its capabilities. Culture is like the brain's software. (Laland, Tomasello, Donald, and others.) So I'm not sure it's perpetually inevitable that people will believe in God or something god-like, as we are becoming less religious as the mechanisms of social governance have moved from the religious domain to secular institutions of justice. Beliefs change with social organization and social organization changes with technological development. Currently I'm sure that a large portion of people still feel they live under the firmament, but more and more are starting to see we live on the planet, this "pale blue dot". What is available for us to embrace is largely an accident of where and when in history we live our short spans. If new beliefs emerge, they are built out of existing ones. (And the idea of the brain-in-a-box, the isolated mind is a product of history, discredited and soon to be discarded.)
People do argue for and against the existence of God, invoking things like the problem of evil, the evidence of the work of intelligence in nature, the necessity or irrelevance of a prime mover, etc. All I'm saying is that the idea of monotheistic God is an accident of a very brief period of recent human history, which itself is extremely brief in the context of geologic history, and although the idea of God is meaningful to some of us, it has no sense without us. What would the monotheistic God be supposed to be without us? Another useful fiction for maintaining social order, now becoming increasingly useless and even counter-productive in terms of justice and human well-being.
