I would ask him why other herd animals treat there own kind with a type of morality code. Why do Bonabos and chimpanzees have developed social mores? Why would human social mores not follow logic and be more advanced befitting our increased mental capacity? Why would he think our human morals are out of sync with the expected level as observed from evolution?
Then I would ask him if he had any morals before he became a christian? Where did he get his morals from if they weren't from his mother and father, who got theirs from their mother and father and so on as would be expected from evolutionary processes. For his morals to have come from god, he would have had to have had them "injected" at some time after birth. Ask him what day god injected his babies with goodness, or were they always good?
