Historical fiction is a story that takes place in a certain period of history but the characters are usually fictional.
Religion is the exact same thing.
Especially if your religions doctrine cannot be independently verified by historians of the time.
That is a very basic requirement. You can make all of the bold claims you’d like in your religious text but if they are true, someone else would have seen it and written it down.
Don’t believe something just because someone says it is true. Find out for yourself. Do the research.
Even if it is your spiritual identity.
Don’t blindly follow anyone.
Ok. Life advice over.
