Mhhh well this is a difficult question. Atheists believe there is no God. So there is no point in religion. From a Atheists point of view atheism is not a religion. From a neutral pov you may argue the believe in no God is a religion of its own.
Agreed, though there is an argument to be said where your parents will raise you in a specific way, based on their upbringing, and therefore your nature could decide your house. Malfoy was a slytherin because his parents were, and that’s all they brought him up to be, which isn’t unlike religion, where being raised in a specific way will decide your outlook on the world
That's the us ngo satanic temple, you also have people who religiously worship satan instead of jesus. Christian multiverse. High chance of encountering cults if you look for them.
Know I'm thinking it just starts letting out prophecies, not answering the question of what religion you get, but rather telling stories of horror about the non-existence of God and yet the ever fleeting reality we are yet to experience.
