My Best Case for God to An Angry Atheist

An atheist named Luis, who had never commented before, recently commented on one of my YouTube videos about unbelieving spouses leaving believing spouses. His comment said that I was one of the worst contemptible pieces of evil S#@! he had ever seen. We traded comments back and forth until finally he asked me to make my best case for God. This was my reply. I never heard from Luis again after this message.
