At least you have a starting point with him.
Atheists think we are idiots and begin with a dismissal if we try to talk science.
ExoPlanets: They cannot be seen, heard, touched, or otherwise detected. Yet scientists infer their existence based on the gravitational effects they have on the star that is in close proximity to them. Yet those same scientists will tell you that God does not exist, that faith is ignorance, because God cannot be seen, heard or touched. They put their faith in man and science. From what I have experienced in my life, I would rather put my faith in God; As science and man have mixed reviews and results, at best.
