There is a case against religion that goes like this: someone born in the U.S. is more likely to be a Christian, someone in India is more likely to be a Hindu, someone in Saudi Arabia, a Muslim.  How can someone say that their religion is true when there are dozens of other major religions that people adhere to because of where they were born?

Now it is true that where you are born will determine how you see the world, and the family you are born into will greatly influence religious beliefs.  However, you almost certainly wouldn’t be an atheist if you were born in Saudi Arabia.  You wouldn’t believe in human rights if you were born in many places in China.  Does that make human rights untrue?  I hope not.

Truth is not disproved by diversity of beliefs.   Ultimately, religion is not just moral rules and rituals but a series of beliefs about how to see the world.  Just like atheism and just like issues of human rights.  And in the same way, Christianity is not true because it is a global religion, but it’s not disproved either.
