This is so stupid. Neither you or the author nor the questioner on Quora are in a posession of a proof about the existence of god.
Really, this is a discussion debated by philosophers way more clever than both of you for more than just centuries. The conclusion is: there is no way to decide on the existence of God by proof. Neither positive (i.e. proofing its existance) nor negative (proofing its non-existance).
