It would be worthwhile investigating what your standard of reality is.
This isn't a cute logical trick.
"Where there is perception, there is deception" as the Buddha said. Anyone who's seen a magician perform can attest to that much
In my opinion, ultimate reality of a deity is not something we can slap a label of thought on like "this is true", because "knowing" of this kind is itself ever-changing, influenced by countless factors and influences, and unreliable.
It's all more mental formations with associated pleasant feelings that contribute to the edifice of a good, clear-minded self versus a bad, superstition-deluded one. The same old five skandhas functioning under the cloak of logic and reality-finding.
To another point, I think it's a category error to say that because a deity is not solid, touchable, and visible in the same way a cup of coffee or anything perceptible by certain senses is, the deity therefore doesn't exist.
The danger in this category error is that "therefore he doesn't exist" nearly always includes the value judgment, "therefore he is useless for my life and can be disregarded."
We'll acknowledge that a friendship between people is similarly not solid, touchable, or visible, yet because we generally give it value, it has function and influence, almost a life of its own.
Certain perceptions and contexts are privileged over others to suit how we understand the world already.
For me, the way Buddhism challenges these frameworks of understanding continues to be one of its most challenging and helpful aspects.
Reality is far more porous than we think is my point.
Insofar as practice with a deity leads to liberation, that is infinitely more useful to myself and other suffering beings than abstractions of reality based on double standards of perception.
