The political ruling classes did a great job of establishing and selling (and forcing) the Abrahamic religions.
There are other religions, such as many of the various African animistic traditions, Shintoism, and Buddism that while are rooted in superstition and irrationality in many respects, seem more conceptually reality-based than those stupid bearded desert pedo

religions, Christianity, Judaism, and Islam, that have brought the world so much strife and division.
I think the monotheistic nature and general tenets of the Abrahamic religions provide a fairly
easy and straightforward structure that is appealing the political establishment as well as to common folk. There's just one God/Yahweh/Allah and he gave you everything you need to know in one Torah/Bible/Quran.
It's very easy to establish an identity and community around that, and act in unison or control others. Say your prayers, eat your vitamins, blah, blah, blah. Then you throw in the Heaven/Hell thing which plays to one of the fundamental and inescapable aspects of the human condition; fear of death; and provides a specific strategy to handle it.
Constantine was shrewd and he knew that.
That's why he established Christianity as the religion of the Roman empire when it was a small cult with relatively few followers at the time. He was tired of constant war and Maxentius coming for his neck.
He knew Christianity could be a stabilizing and unifying force for his people to win the war and keep his empire together, moreso than that loosely-connected barbarian cult shyt the Romans were on, so he made up some bullshyt about seeing a cross in a dream so he can consolidate power and control via the use of Christianity as a legal, military, and economic entity.
And now people in America today tell you you're going to hell if you don't get saved. Constantine trolled you nikkas.
