I want to know the answer to the following question:
Who argued that the existence of God is an empirical question?
All the background I'm provided with is that "Carl Sagan argued that the doctrine of a Creator of the Universe was difficult to prove or disprove and that the only conceivable scientific discovery that could disprove the existence of a Creator would be the discovery that the universe is infinitely old.". Is that enough to answer the question?
Answer: no
