The problem is that what you are all basically saying is that a being that's believed to be a god is considered a god.
By that definition everything is a god.
In some real-world religions and the in-game belief in CHIM, that is the case, yes.
Are you a god if someone believed you to be?
In the real world, that depends on how you think that works. In TES, yes, belief feeds back on reality and makes itself true.
Look, think of it this way. before Abrahamic religions came to power a god was an anthropomorphic personification of natural forces. Powerful, yes, and able to be staved off but never truly stopped short of destroying the part of the universe that it was. A good example is Norse Ragnarok. The gods die, and in the process the universe itself is destroyed because the gods are representations of parts of the universe. It's no coincidence that after the death of Balder everything is grimdark and melancholy. In TES, Talos is the representation of heroism and the human spirit, Akatosh is himself Time, Mehrunes Dagon is in fact destruction.
But really, you are using a specific proper noun (God) and trying to apply that definition to a general noun (god), and seem to be getting a little upset that we're pointing that out to you, moving the goalposts when it suits you, pretending people didn't post counter-arguments and using several other logical fallacies.
