I never really understood what the difference between an athiest and an agnostic was...I mean I know atheists are supposed to say there is no god and agnostics say I dont know, but I dont think most atheists say they know theres no god, just that they havent been presented with any evidence of any god and we dont believe in that. To me its the same thing. You cant even say conclusively transformers or smurfs dont exist unless youre omniscient.
For the most part, an atheist will definitively state that a Power does not exist until proven. You'll get a whole variety of them across the spectrum from really-fairly-agnostic (as you described) to the definitive "no."
Agnostics have been called mushy by atheists, but it's a refusal of the "no" position that's in question. There's quite enough room, for instance, for a purely Deist God in the agnostic's viewpoint. We prefer to state, "We don't know, and we're comfortable with that." There's a similar spectrum here from "probably exists, but I'm not sure" to "probably doesn't exist, so functionally an atheist."
Christians and the other Abrahamaic religions are gnostic in nature. They claim to know--but are chary with the proof on the matter. Some state that proof is impossible, which any good agnostic or atheist will tell you is hogwash at worst and sidestepping at best.
I'm agnostic on this point as I'm agnostic on whether there's a comprehensive cure for cancer or whether type M stars go through a blue dwarf stage at the end of their lives. I simply don't know, and neither does anybody else yet. I'm less agnostic on the latter than the former; modeling does indicate that a blue dwarf will happen and I'm familiar with that. I'm more agnostic on the former as I don't known enough to render an opinion on the matter.
I'm not agnostic on things like homeopathy; experimentation shows it does not work, so I'm a-homeopathic.
You'll find that most agnostics tend to extend this to a fair number of things, but as always, there are plenty of exceptions and "most" in this case is only a plurality, not even a bare majority.
