In what manner were they physically incapable of educating themselves?
By not having ready physical access to any of the information involve in such education, nor any reason to believe that such information exists or has any value such that they can't be reasonably expected to go out of their way to find it. If you're born, live your life, and die on an island thousands of miles away from any record of Christianity or its teachings, how could you possibly know anything about the Christian God?

Some sects of Christianity are athestic? Perhaps you meant aesthetic.
Atheism is the opposite of theism, which is the belief in one or more gods. Atheistic Christianity would be a belief in Christian teachings, but not ascribing them to an actual God figure so much as to the spirituality of people and an abstract "natural order" of the world, as an example.
