I agree with the heretics. The god they hate so much does not exist: a god who looks through the clouds at a world he once made, and plays with it from the heavens, like a child plays in the sand...
Such a god is nothing more than another toy of Man. A man has a house, a car, a job, a wife and children. Therefore, he must also have a god. And he creates one in his own image.
God is not a creation of the human mind. God is the reality in which we exist.
