{_𝐘𝐋𝐋_} Well, if anyone in a religion truly belived it with every part of their soul, they would think it’s the one truth. Not that people intend to brainwash the world, they just want everyone to know the same truth that they believe in too.
(This part isn’t directed at anyone specific)
Other religions were created because not everyone felt like they had the truth. They wanted to seek it. It would be a completely different world if everyone on earth knew the one true religion. Even if they didn’t want to believe it, just if everyone knew what it was. But the world is full of boubt. And people want to feel uncontroled by a higher power. It’s kind of like a teen not wanting to listen to their parents. You can do whatever you want in an unmoral aspect, but inside, deep within, morality is a thing.
Maybe you’re athiest, and you’ve never experienced finding truth in any religion at all. Maybe you think the world itself is all we have. No such thing as heaven, no such thing as hell. No such thing as gods. No one beyond what we see with our eyes. Im not sure how independent you think you are, or how grim that life could really be, but I cant and am not trying to tell anyone what to believe.
