How to argue against this claim

[Brian37]

If religion brought worldwide peace to the world as all religions claim, we should have expected to see it by now.

Christianity doesn't claim that it will bring worldwide peace until after the final judgement when God will create the "new Jerusalem", the new earth. We strive for peace, but as long as evil exists on the earth, there won't be peace.

Dude every religion claims they are the shit. Every religion claims details make them unique and thus the inventor of the universe and human morality.And you like every other religion with other god claims are fooling yourself.

Christianity was not around 200,000 years ago, much less 4 billion years ago and much less 14 billion years ago. No religion was.

And billions of years from now our species will go extinct and the planet's core will die and our sun to will eventually die and the universe will go on with no record of our existence.

Your religion is like every other religion, a product of human imagination do to gap filling and selection bias. Christianity is not special, nor it is the center of the planet or the universe. It is merely something you swallowed and like believing.

No, there is no afterlife, that is simply a claim in a book of myth you swallowed. While there is no heaven, the good part is that there is also no hell either. No, it is not a license to be lawless or cruel, just an acceptance of reality. For the same reason you live your life fine without belief in Allah or fearing the threats of their hell.

FYI the "Judment" motif is found in ancient Egypt long before Christians and even Hebrews existed.

The reason humans do not have peace is because we compete for resources and use religion, politics and nationalism as excuses to claim moral superiority. We will never live in a perfect world, but our species could have more peace if we would see ourselves as the same species instead pretending the religions we belong to are hot shit. Instead humans need to see them as personal likes. But not you or anyone gets to be free from scrutiny.
