Amazing how most people who are born in christian countries have christian beliefs. Its mind blowing. Clearly, it must all be true just because of this.
There is nothing mind-blowing about information sources.
This is a logical fallacy - “The Genetic Fallacy”.
This fallacy is made when someone attacks a belief or an argument by pointing out how the person came to hold that belief (its genetics). The fact of the matter is, if I’m giving an argument for the existence of God, such as the Kalam Cosmological Argument or the Fine Tuning Argument, maybe we’re having a discussion on the historical evidence for the resurrection, the country I was born is irrelevant to whether my arguments are good or not. You can’t refute a belief by showing how a person came to hold that belief.
