I didn't watch this video. But have studied the fall of Rome.
The fall of Rome was far more complex than religion. And religion was not one of the major factors.
It may have been the final blow for the Byzantines, but it was not the cause of their fall, and had very little to do the the split.
Until the end, Rome embraced a multitude of religions, and generally didn't care. That didn't change until Constantine, and Rome had already fallen.
There were many causes working toward the downfall of Rome. The biggest were decadence and a firm believe that Rome was too big to fail.
Religion may have been on the list, but it wasn't near the top.
Here's a simple summery that may give you a better idea of the causes.
History channel has been known to do shady things in the past: https://en.wikipedia.org/wiki/History_(U.S._TV_network)#Criticism_and_evaluation
I know religion was the reason because this happen when religion was just starting to become a thing to everyone else. it was not just Rome, many other like India or China also fought for religion within the timezone of "fallen Rome".
The main point is that people in those times knew which religion was real and which was fake. Even today we know Christianity was not built by god(s) but by people, its roots are with Islam.
Dude, no.
Seriously, no.
I didn't learn it from that article I linked. I linked a short summery for you to learn from.
I learned from years of study. Books and classes on ancient civilizations.
Do a google search and you will find every credible source will say religion played either no part, or a small role.
That's not my opinion. It is documented history.
happen when religion was just starting to become a thing to everyone else
No. Religion has been around thousands of years before we started to write. When Rome was founded there were already many religions across the world.
Rome fell because of many religion clashing and fighting. We have historical records of people and empires fighting over religion in Rome. This video did not explain anything about that nor did it reference many empires in Rome that did fight over religion stats.
I think this video is another crazy fan theory with zero evidence or reference to historical events.
