See you are either a theist (one who has theistic belief) or an atheist (one without theistic belief). Theists will answer yes if you ask them whether god exists. If you say we can't know whether god exists, then you lack theistic belief, are not a theist, and therefore are an atheist.
To repeat in a slightly different way, theism is the root word we are concerned with here, meaning belief in god. When an "a" is appended to it, we get the word atheism which means without theistic belief. Now you can't very well believe in god (be a theist) if you believe it's impossible to know if god exists, can you? Makes no sense. And if you lack theistic belief you are literally an atheist. Hence, agnostics are atheists.
Sorry, that's just how language works.
