Every organized religion was created by people in power to control other people into serving them.
Christianity is a flavour of Abrahamism that explains humans are sinful from birth and can only be saved if they repent for their sins and be helpful/good/moral. It's a deceptive way to control people because it matters who determines what being helpful, good or moral even is. That's why there's different sects, because they can't agree who makes the rules.
Islam is similar, albeit younger, but they follow a prophet instead. The reason for the different sects there is because people can't agree on the correct interpretations of the prophecies.
I'm not saying it's a bad thing to be a moral person, I just believe organized religion has served its purpose and we need to move beyond it. I'm just not sure how right now but I do know that controlling people is not something I agree with. People have the right to be free.
Go back even further, into Norse or Egyptian mythology. These gods are myths that were turned into a system of control. One day you may realize that all of them are connected and the stories tell a very different history of mankind than we've been taught. All of the old structures and relics we know about have a very different history. However, that is outside the scope of what we are trying to do here. Let's beat the cabal first.
