TL:DR zinger - no god manages to transcend its culture. It is therefore true to say that no being worthy of the title of god has yet been discovered.
The concept of beings greater than ourselves and able to do things we cannot is a fundamental aspect of our psyche ( possibly due to having evolved from animals with alpha male organisation - everyone else is subordinate.) We use that idea throughout our literature from Harry Potter throught to Allah. For an idea to survive it must be transferred to the children. Supernatural tales that are written down survive the passage of time best.
Our supermen ( and most supernatural, super human imagined creatures are men and where the few women are elevated it normally revolves around their ability to create things) explain our culture and use elements of our world ( kids from an Amazonian jungle tribe would never conceive of Harry Potter.) No imagined being transcends or rejects the culture they were created in ( so hebrew god Yahweh is cool with animal sacrifice, genocide and slavery.)
Each culture finds it easy to dismiss another cultures' supermen (JWs being 'Christian' and this site being in English gives us a westernised slice of the Christian worldview hence the gods we discuss here are Jehovah / Christ based. Even our forum believers would agree that Brahma is not real. Western civilisation and its embrace of science , rationality and logic has shattered the original hebrew god so thoroughly that it has had to reimagine it's gods ( hence we now discuss deistic gods within the same umbrella as the literal bible god.)
When we discuss evidence for and against the god we are actually discussing evidence for and against the culture of that god. Thus it is almost impossible to not be rude ( a god wouldn't be fussed about underlings but a believer will quite rightly get offended when their imagination / culture is getting strongly critiqued) and to reach a satisfactory agreement. Once a believer becomes a preacher the emotional and social cost of failure become very, very high hence the number of people adamantly proclaiming that the emperor is clothed.
