Are there Christian responses to Leonard Susskind's agnosticism, which is based on his view of God as a mystery hidden behind a "curtain"?

[Leonard Susskind - Wikipedia](https://en.wikipedia.org/wiki/Leonard_Susskind) : > Leonard Susskind (/ˈsʌskɪnd/; born June 16, 1940) is an American theoretical physicist, Professor of theoretical physics at Stanford University and founding director of the Stanford Institute for Theoretical Physics. His research interests are string theory, quantum field theory, quantum statistical mechanics and quantum cosmology. He is a member of the US National Academy of Sciences, and the American Academy of Arts and Sciences, an associate member of the faculty of Canada's Perimeter Institute for Theoretical Physics, and a distinguished professor of the Korea Institute for Advanced Study. Susskind was interviewed for the program [Closer to Truth](https://closertotruth.com/video/susle-002/?referrer=8041) , where he explained his reasons for *agnosticism* regarding the question of God’s existence. The video lasts 7 minutes (you need to click on the *Long Video* option in the *FORMATS* section), but below is my attempt to summarize the essence of his reasons for being agnostic: > Susskind is agnostic about God because, if God exists, He remains hidden behind a metaphorical "curtain" of knowledge. In front of this curtain lies all the scientific understanding we have accumulated from studying nature, while behind it are open questions we have yet to answer—such as the origin of the universe, what happened before the Big Bang, and so forth. Susskind believes we currently have no way to investigate these mysteries, including the concept of God. For him, God is a hypothesis that cannot be confirmed or falsified by any known scientific means. Since the question of God remains undecidable and beyond our current ways of acquiring knowledge, Susskind remains agnostic. Are there Christian responses to this agnostic perspective, which views God as a mysterious hypothesis hidden "behind a curtain" and beyond the reach of scientific investigation? What might Christians suggest to someone like Susskind, a theoretical physicist, as a meaningful way to "investigate" God beyond the limits of scientific inquiry?
