the dunning kruger effect deals with the fact that the more a person knows the more they realize how little they know.

what do you think this says about someone who believes that he can know everything?
That effect can be interpreted in more than one way in this context. E.g.:
what on earth are you talking about. atheism doesn't claim any knowledge about god. in fact its almost the exact opposite of what you just claimed that it was. it is the claim that people ought not claim to know that god exists. break down the word. a-theist, opposition to theism, opposition to belief IN god. this is not a claim that god doesn't exist.
this is the great lie about atheism.
Even the most brilliant men in the world are specialists, collectively we can know much, but individually we rely on others as do all atheists, they trust and worship the viewpoints the greats among them. Atheism does have a belief system, core values, and strong belief in how life is created and what moral fabric we should wrap ourselves in, just like any religion does. Those things would only become more developed and uniform as atheism progresses.
In time, were Atheism to take over the planet, everything about Atheism would look exactly like what we call a cult today. If you showed any sign that you were a non-non-believer you would be outcast or worse.
and in that strange atheist future world, the mystery of what give chemicals life will still be a mystery and and still be a miracle
