If you were born in a totally muslim country would you still have been a christian?

Why not?  Untold millions of people born in Muslim countries have become Christians.

Vastly unlikely.  

Unlikely.                             

Hard to say with certainty, as I do know people born Muslim who are now Christians.

If you had been born in a Muslim country, would you still be a heathen?

Religion is a choice. It isn't something you are born into. Being born into a Christian family doesn't make you a Christian. Being born in a Christian nation doesn't make you a Christian. What matters is that you make the deliberate choice to accept Jesus Christ as your Lord and Savior. Even if I was born and grew up in a Muslim country, with Muslim parents, I would still be a Christian because I made the choice to make Jesus my Lord and Savior. 

Who knows... there is always that possibility.

Religious people are group-think people.  They adopt whatever the group believes.  They believe it's true because the group thinks it is true.

No. You be Muslim. But that's not a problem because Christianity and Islam and Hinduism and many other major religions only differ in insignificant details. Don't let anyone deceive you into thinking there is a real difference between these religions.

Many Have converted to Christianity, to their own peril

Cannot keep the truth down
