Why people are religious

[Angrboda]

Yeah, but that came to be in some way. You haven't been born with the catholicism is true gene.

Very true. So then the real question is, why do religious people believe their religion is true? That's a long answer. At least for me. As has been said by Vic and King, the answer changes from person to person based on their own personal journey, and making simplistic assumptions and generalizations is counterproductive to understanding people's motives.

Unless there happens to be a unifying explanation which accounts for all the facts. If that is the case, then emphasis on understanding people's "motivations" would be a red herring which would obscure the truth.
