My position is that I don't know, and that by the evidence I've seen and the arguments I've encountered, I have no reason to believe that the Christian God exists, and the same goes for all the supernatural claims of the Bible, I also have some reason to assume that these claims, such as God, the Soul, and the Afterlife, are not possible (for all three of them, the belief that the mind and senses could exist without a physical component is a serious obstacle that needs explaining away, even if you reject the soul/afterlife and accept bodily resurrection, the problem remains as God is still in the picture, all it does is adds on the problem of how bodies decompose and their constituent atoms are used for the construction of other lifeforms, including those which "count" such as future human beings), but that is subject to change. As such I am in agreement with you, there is no reason for the term of agnosticism to exist, it's origins are jewish, and comes from a jew whose influence I particularly despise, and what it describes is the position that was held by the majority of atheists throughout history, when someone calls themselves "atheist" chances are that this "agnosticism" is what they are talking about with regards to their position on religious claims, those who outright deny even the possibility of religious claims are not very common in my experience.
