Nevertheless, conceiving of God as all-powerful, all-knowing, and perfectly good makes the existence of evil a basis for formulating such arguments.

Whether the argument is sound is, of course, a further question, for it may be that one or more of the premises is false. The point here, however, is simply that when one conceives of God as unlimited with respect to power, knowledge, and moral goodness, the existence of evil quickly gives rise to potentially serious arguments against the existence of God.
