Omg, I love this question! I often wonder how my beliefs would differ had I been raised by a different family or in a different place. Would I come to believe in any religion I was "born into"? I think it's the same as being born into an atheist family. Your nurture programs you to not believe. Of course, people change their minds. We don't all agree with what we grow up with. Often it's quite the opposite.
Were Africans born into the right skin or was it a coincidence that they were born into the colour of the original skin that humans have..
You see every religion comes from one original truth, just like every skin colour comes from one original colour, one cannot say that this race is the real race but one can say that this race is the original race..
Just like religions you don't have to be the first religion to speak the original truth of the original religion, but if you speak the original truth then you speak the ultimate truth..
