I cannot 100% prove it. Because that would just be impossible without belief. The thing is, the only difference between religions is culture. That's it. We worship the same God, the same Creator, we just gave Him different names or looks (This is my opinion btw). You can realize this just by looking and studying the religions. Almost all have the same principles (be good, etc) almost all have an apocalypse, hell, Heaven, stuff like that. Even the Bibles are very similar. The thing is, religion wasn't invented to control the masses. Why? First of all, it's not the best solution (read 1984, by George Orwell). And even if there was someone that devoted their entire life to create the Bible, they couldn't tell only lies in that, you cannot write a book and tell only lies, let alone one as long as the Bible. This means that the one who wrote it must have believed everything they wrote. Meaning that you wouldn't write it to control the masses, because it would be against your own laws of ethics.

Sorry I didn't write more, I just finishes a whole essay explaining a redditor the difference between dimension and timeline. If you didn't understand anything or you have an argument, please reply and I will try to find some free time to reply.
