For the record, I treat demands for evidence for the existence of God the same as demands for evidence for the existence of a round earth or man-made climate change.
It's not that I can't prove what I believe to be true. I can! It's just explaining it would prove too time consuming, especially since the person demanding the evidence is evidently asking in bad faith.
In short: I'm not wasting time and effort attempting to argue with someone in bad faith.
If someone is trying to tell you what you believe rather than ask you, that person is acting in bad faith and you do not need to humor them.
