trying to prove the existence of God

Which he couldn't/didn't do, giving credence to my position that you don't come to belief in god through logic.

Look, I spent 40 years working with literal rocket scientists, I understand that smart people can be religious. Literally zero of them were raised without religion and came to it because of logical deduction. Smart people will either try to justify things they were raised to believe, or they'll just say that their religious beliefs come from a faith that isn't tied to logic. But rocket scientists who were raised Hindu will do the same with their pantheon as Christians do with their god.
