Abstract
I argue that Ireneusz Ziemiński doesn't justify his skepticism about knowledge of existence of God. First, he reduces a question to metaphysical one - do we have sound, valid proofs of God's existence and imposes too heavy conditions on arguments for God. Second, he doesn't show that disagreement between philosophers in that question justify his negative assessment of arguments. Third, Ziemiński omits epistemological question what is knowledge of God's existence, especially in its direct form as well as externalistic account's of knowledge of God, for example Plantinga's and Alston's.
