Wizzstick,
The Dictionary.com defines "deity" as: "1. A god or goddess 2. divine character or nature, especially that of the Supreme Being; divinity 3. the estate or rank of a god 4. a person or thing revered as a god or goddess 5. the Deity, God; Supreme Being."
I gave you one possible definition of deity, attested by a definition that can be found in a dictionary. I gave the example of Augustus in ancient Rome, and the cult of the emperor. And yet, you refuse to accept it as a valid example of a deity that empirically existed. You or I may not personally ascribe that deity any special power, but millions of people in the ancient roman empire did. It's therefore, a relevant example.
