The idea that God is invented, if true, logically means everyone is an atheist since an unreal, invented god is no god at all. If you believe in no god at all then you are an atheist. If everyone is an atheist, where is atheism? There is no need to call it atheism since it includes everyone and something that includes everyone needs no name. So by using the word atheism, atheists prove that there is a god who is real. Not invented.
