Why do people believe in God?

I’ve always been curious how a set of basically bronze age values came to be a part of our modern technological world. People can believe what they want, im not trying to pi/ss on anyone’s beliefs. Im just curious why it is so.
In almost any other area of life people ask for proof to believe in something, yet a lot of people accept a God on total “faith” alone.

There are some obvious reasons. Some people could just be brainwashed the same way people will be brainwashed by charismatic cult leaders and cults. Some people will just go to Church, and get spoon fed the “evidence” from one side, and lead their lives never knowing the “evidence” they are getting is flimsy or non existent. They’ve got bills to pay and a hectic life, and they want an easy quick answer. Some people might think it’s mum and dads religion, and it was good enough for them, so it’s good enough for me, and whilst the religion might have some bad points it’s really got a good heart. It also gives them a sense of belonging. Some people might hit really bad points in their lives, and need hope. Some people might need to think they need a reason for their existence, and they dont wanna think they are a random fluke. They also need a set of morals and laws to follow. Some people might lose loved ones, and be comforted by the thought that they are in a “better place” and they will be reunited. Some people will wanna feel that justice will eventually be dished out to the wicked and evil. Some people will look at a tree or blue sky, and think it’s evidence of God, or some people will look at the complicated universe, and wonder how something can come from nothing, and give the “god in the gaps” argument the same way the argument was used when people didnt understand lighting or natural disasters or anything else. Some people might reach PB’s age and realise the Grim Reaper is heading from them, and they dont wanna think they are gonna rot away in a coffin.

The list is exhaustive, and it could go on all night. I think one or more of these reasons would apply to a lot of believers though.
I dont know enough about other religions, but I believe Christianty exists as a force in our present world through sheer luck. It won the religion lottery ticket. In any contest someone has to win. We need religion, and Christianty emerged victorious against all the other similar religions at that time. It would probably have been a footnote of history and we would have believed something else today if Constantine hadnt seen a vision of a cross before a battle, saw it an omen, and when the battle was won decided to turn his empire (a huge chuck of the known world at that time) to Christianity, pretty much whether his subjects liked it or not. At that time Christianity would have had the power to do anything it liked. I think that’s the luck aspect. After that it’s just a case of passing it from generation to generation.
People of the past would also have seen it as their duty to believe what their parents and grandparents believed, and they probably just didnt have any information to contradict their beliefs. They would also probably have been far more prone to believing in superstition.
You have to wonder in our modern world with so much information freely avaliable, and people less prone to believe stuff on faith alone how long Christianity and the other religions will endure. In 500 years time will they still be around or will they be treated the same way Scientology etc is today?
