But, as soon as God is defined, then it is no longer necessary to prove a negative, only to prove the God just defined is not possible. When someone asks me if I believe in God, I always ask, "which God, Allah? Shiva? Zeus, Dianna? A Greek God" a Roman God, a Norse God, which?
Usually they tell me, "the God of the Bible," which they think gets them out of trouble, but it doesn't, so I have to then ask, "which God of the Bible, the Unitarian God of the Bible, the Tirinitarian God of the Bible, the Mormon God of the Bible, the Gnostic God of the Bible, which?" ...because these all define God differently.
This usually leads to an absurd statement like, "God cannot be defined." So, I ask, "do you believe in Morkano?" When they ask what that is, I say, "well, it cannot be defined, but what difference does that make. Its just like your God, only different. The only reason you don't believe in Morkano is because your refuse to. You're just an amorkanoist."

That's true.
It seems, though, that your argument is vulnerable to a nebulous definition - for instance, that God created the universe. The Deists believed that God's "testament" was in His works, which we see all around us.
On that basis I think you'd be left trying to prove a negative.
One of the best treatments of this argument (in fiction) is the novel Voyage From Yesteryear by James Hogan.
