Agnosticism allows to say 'I don't know' in order to build a bi-optional foundation. Let's find out without any bias, and let faith help those who need it.

Atheism does not mean a person knows for certain there is no God
Atheism is simply a rejection of any (or all) specific Gods...
Christians say their God exists... I don't believe them... I'm an Atheist... same goes for Hindu, Muslim, etc... I don't believe any of them
To compare it to a courtroom... Atheism would be finding the defense, "not guilty beyond a reasonable doubt" (you have not proven God exists)... which is different from "innocent" (God does not exist)
Atheism is a statement about belief, and Agnostic is a statement about knowledge... the two are not mutually exclusive... (you can be an Agnostic Atheist, or a Gnostic Atheist... just like you can be a Gnostic or Agnostic Christian)
Also, nobody knows for certain (everyone is an agnostic)... anyone who claims to know for certain is a liar or a fool
You might be right though .
At least I can see your point
