Because religion provides comfort, community and a meaning to people’s existence that goes beyond “we were born of chance on an insignificant rock somewhere in the universe”.
(I’m not religious BTW)
Childhood indoctrination is a big part of it. I have been told by my 8-year old niece that she’d like to save me from drowning in a lake of fire. She was genuinely scared for me. It’s literal child abuse followed by Stockholm syndrome.
Have you heard of the fireplace delusion? Burning wood is horrible for our health and the environment, but most of us have fond memories of sitting by a fire. Religion is the same. Holiday traditions with family, organized events marking important life events, it’s hard to break away.
Religion has certain self-reinforcing properties. Kind of like genes that make it more likely to propagate against other forms of information.
- Believing without question is better than questioning
- Not believing will be punished
- Virtue will be rewarded
- Spreading the belief is a virtue
- You should obey your parents
Combine that with young human brains being malleable, and religion tends to continue against all odds.
