it is better 2 call babies who are just becoming aware, as agnostic than atheist

Well, public perception can be a tricky matter, as it is not always entirely precise. Especially when regarding subjects like this. For the definitions, in regards to Atheism: Merriam-Webster(as I think you already quoted): a : a disbelief in the existence of deity b : the doctrine that there is no deity Drawing attention to "a", in particular. American Atheists define it as "a lack of belief in supernatural beings" therein not necessitating knowledge of those beings. Oxford Dictionaries defines it as "Disbelief or lack of belief in the existence of God or gods." Again, not necessitating knowledge of those gods. Urban Dictionary: 1.) A person who lacks belief in a god or gods. People who use this definition categorize atheists as either negative (or implicit or weak) atheists or positive (or explicit or strong) atheists. Negative atheists, while they don't believe in a god, do not positively assert that no gods exist. Positive atheists, however, do. 2.) A person who believes that no god or gods exist. Those who consider themselves atheists (who are usually positive atheists) tend to define 'atheist' using the former definition, and those who believe in a god or gods tend to define 'atheist' using the latter. In both cases, this seems to be a demagogic practice intended to classify either as many or as few people as atheists as possible. Negative atheists are usually referred to as agnostics. None of these necessitate that an Atheist must reject the notion of there being a God(as that requires knowledge of the concept) As for Agnosticism. The Wiki states it as "...the view that the truth values of certain claims"especially claims about the existence or non-existence of any deity, as well as other religious and metaphysical claims"are unknown or unknowable" Merriam-Webster states: : a person who does not have a definite belief about whether God exists or not : a person who does not believe or is unsure of something And finally, Dictionary.com: agnostic ag"nos"tic [ag-nos-tik] Show IPA noun 1. a person who holds that the existence of the ultimate cause, as God, and the essential nature of things are unknown and unknowable, or that human knowledge is limited to experience. Synonyms: disbeliever, nonbeliever, unbeliever; doubter, skeptic, secularist, empiricist; heathen, heretic, infidel, pagan. 2. a person who denies or doubts the possibility of ultimate knowledge in some area of study. 3. a person who holds neither of two opposing positions on a topic: Socrates was an agnostic on the subject of immortality. adjective 4. of or pertaining to agnostics or their doctrines, attitudes, or beliefs. 5. asserting the uncertainty of all claims to knowledge. 6. holding neither of two opposing positions: If you take an agnostic view of technology, then it becomes clear that your decisions to implement one solution or another should be driven by need. I believe, from what I am aware of, that Agnosticism requires that one is aware of either argument. For one to decide that something is unknowable, one must be aware of the concept of that "unknowable" thing. For one to reject either side of an argument, one must be aware of said argument. A babe is not privy to the information of the argument surrounding the existence or inexistence of "God", as it is unaware of the concept of "God". Therefor, it does not believe in a god, therefor it is an atheist. And that is my argument. I hate it when an argument hinges on the the questioned definition of a word.
