@Ieldra: Prior to their creation - would it have been ignorance to believe in a race of malevolent creatures that poison the land with their very existence? You might say yes - but it would have been that crazy person that would have been right and you wrong.
Magic worlds don't operate on the same paradigm as our real universe... things literally can just "pop" into existence on a macro-scale. That can't happen for real in our world.
As for the difference between a "god" and a mage and a mundane - I think it comes down to ego to not want to see what I consider painfully obvious differences.
A mundane man in a fantasy world operates largely like a real human would. He lives, he struggles, he dies.
While it's not as true for DA mages - wizards tend to be actually in tune with their fictional universe. This makes them genuinely more perceptive than the average man can possible be. Real humans in our world could never see an atom... or a molecule ... or a million other things we use machines to draw images for. A mage "can" train himself to do these "type" of things in the ficitional universe. This type of human does not exist in the real world.
A god must be a being. Abstracts begin reaching into the realm of what people like Einstein meant when he talked about god... our best real world terminology for an abstract, non-being, god - is Nature (in the East it is called the Tao). The force (sapient or not is not relevant) behind all existence which we named for the sake of convenience but which is so entirely vast that all it's systems encompass everything there is, was and will be.
This being, which we call a god, must have a form - even if that form is "formless". The Form of a deity is it's aspects... Creator, Destroyer, Agriculture, the Sun, the Moon, etc. etc. It must possess powers. But it need not "live" "struggle" or "die" in the sense of a man or a "mage" or even the fantastical creatures in the universe it inhabits (like a dragon). They are beyond the rules - and the rules often exist because of them. A god, is an idea, with a form.
Logical arguments like everything comes from something are pointless... because it is a fictional universe... they do not. Any rules, others than the rules imposed by the creator, are irrelevant no matter how many "fans" threaten the creator with name calling like: This is stupid - if you knew what you were doing you'd do it like I say.
