That’s a big question. Different atheists will use different arguments, but they often confront Christians with two things: (1) Darwinism has refuted the idea of Designer and so defeats Christianity (and every other form of theism). They claim that undirected, purely material causes and entities can explain all of biology.

This is called the problem of evil.

I’m not going to fault Groothius for saying nothing about the argument from physical minds, but I am surprised he neglected to mention reasonable nonbelief.
