Most Indians are Hinus, most Iraqis are Muslim, and most Mexicans are Catholic. When nations invade or suppress other people, they usually give in to the cultural tendencies of the invaders. As a result of this, most of the Middle East is Muslim and most of South America has become Christian.
If everybody had a legitimate chance at realizing the reality of God shouldn’t we have expected to have seen large bodies of native Australians or Americans that were already monotheist? Instead, it seems many of them subscribed to whatever local variation of religion was available. Today, the world hasn’t changed much. Many people live and die with the faith they were born into. Are they merely unthinking or suppressing a reality they know to be true? Do people in Christian nations have an advantage over those in other countries?
*Disclaimer: this is not a criticism of Christianity, I just want to know people’s thoughts
