Veritass said:You are at the least very presumptuous to state that you might know that "There is no such thing as God." At the very least you might want to qualify it as "I believe there is no such thing as God." It is quite possible that God exists outside of your knowledge or experience.
"There is no such thing as God" is a perfectly valid standpoint. Its simple an ignostic viewpoint, that the concept of God is meaningless and incoherant.
