Interestingly, the only religion that adresses and recognize this phenomenon. Is Islam
Allah in the Qur'an describes people following the traditions of their ancestors and challenges them to examine beliefs critically rather than blindly imitate them.
The epistomoligical thing to understand is
Whether a belief is true depends on its arguments, evidence, and coherence not how many people inherited it or where they were born.
So the geographic argument may explain why people initially adopt a religion, but it does not determine whether the religion itself is true or false.
The geographical location of your place of birth always determine the religion/belief you adapt. Ironically, this always turns out to be the only right and true religion,and with the only TRUE god, while the rest are untrue, fake, illogical, asinine, and made up nonsense. Tragic!
