In 2016, Grayling debated Rabbi Daniel Rowe about the existence of God.
According to Dr. Michael Egnor, "Rowe devastated Grayling."
Atheist Jerry Coyne said of the debate: "I have to admit to finding the prospect of an orthodox rabbi holding his own in a debate with Dr. Grayling on God's existence rather disheartening, but I'm afraid that's exactly what went down the other night in London.
