I believe it is impossible to be an atheist due to the fact that, an atheist will profess with utter conviction that they do not believe in God or a god, but by simply saying that there is a G(g)od that they don’t believe in, they are admitting the existence of a G(g)od.  In other words, they are saying there is a G(g)od but they don’t believe in him.  Ridiculous!
