Religion | The Realization Argument

Would God damn those who know nothing of his existence?

Religion and God's existence have been subject of intrepid controversy for thousands of years succeeding the many establishments of Religious cultures. I will argue against the existence of a super-natural being with a simplistic debate; The Realization Argument

Say a nation/individual is isolated on a separate continent or secluded from Religious Society, like an Eskimo race or solitary island dweller, and has not been 'enlightened' by the truth of Religion. Thus they are not exposed to Religion and therefore cannot follow its regulations on any ground apart from those of primitive instinctive foundation, being the founding of a belief of a 'Super-Natural' being based on a sensation of overwhelming belittlement by an omniscient, omnipresent being or spirit.
If we regard Christianity as an example of a Religion that a race is hypothetically, seemingly excluded from, how could they possibly establish a knowledge of the Bible if they haven't been exposed to its' commandments? How will they define a super natural being, obtain Heaven upon being deceased & avoid the depths of Hell? The answer is that they cannot because their culture has not yet defined a being or culture of such characteristics, or been exposed to it. The human mind cannot be initially configured to indicate that 'Christianity is the path', it is primitive and inhibits only intelligence based upon the fundamentals of human nature; Survival.
Ever heard the quote 'God is good to those who have faith in him'? How realistically could a solitary race possibly exert faith if they lack the knowledge of the Religions existence? God is not good if he damns those to the fiery pits of Hell based upon 'Lack of faith' when those individuals had no knowledge of his existence.

God sent his son, Jesus to earth as a messenger of his Faith, a metaphorical, sacrificial lamb for Humanity, who then expects humanity to 'Have faith in his Religion' based upon that relinquishment of life.
If people know not of this sacrifice, then how may they appreciate its intention? Jesus surely did not expect the word of Religion to have been common knowledge within the Global demographic. A Baby is not born with the knowledge of God, it is taught the methods of Religion progressively through its life, influenced in a way to be inclined to exhibit belief in Gods' name. Some people are not exposed to these teachings, just merely the human instinct.

Would God damn those who retain no knowledge of his existence? Something seems illogical. Religious belief is not inherent, it is an alteration of a mental predisposition to accommodate a specific belief.
