Your evidence is built on assumptions, not facts.
My evidence is the facts about Baha'u'llah, what He was like as a person and what He did in His life, as well as what He wrote. There are no assumptions.
You don't need to believe in Baha'u'llah if he actually lived. It's a fact he was a real person. We don' t believe in facts, we know facts are true.
I meant that I believe that Baha'u'llah was a Messenger of God because of the facts about Him and His mission.
Then Truth isn't factual. So using the word "Truth" is misleading.
The Truth about God isn't factual because NOTHING about God can ever be proven as a fact.
Who authenticated them? Does this mean they were actually written by Baha'u'llah, but not they they are true?
Baha'u'llah authenticated them when He stamped them with His official seal. It means we know for a fact that they were written by Baha'u'llah. Whether they are true or not is for you to decide.
Don't rule out that he could be mentally ill. No rational person believes what a person says just because they say so.
Of course no rational person believes what a person says just because they say so. I do not believe in Baha'u'llah because He claimed to be a Messenger of God, I believe because of the evidence that supports that claim.
I ruled out that He was mentally ill since there is no indication that He was mentally ill, thus no reason to think so.
On top of that these are rather fantastic claims, so they need extraordinary evidence. There is none, as you admit.
What is extraordinary evidence to one person is not extraordinary evidence to another person.
I never admitted that there is none. Baha'u'llah performed a lot of miracles, but why would you believe that unless you witnessed them firsthand?.
Your beliefs are not based on facts, that is why they are rejected.
My beliefs are based on
facts about Baha'u'llah. They are rejected by atheists because those facts are not good enough evidence for them.
That isn't projection. I suggest even you dont understand why you believe, as above you claim to have valued facts for belief in your beliefs, but there aren't any relevant facts to suport the belief you have about the suvernatural bits.
You are correct that there are no facts that prove the supernatural bits, such as the Baha'u'llah received communication fro God. That can never be considered a fact since it can never be proven. It must be accepted on faith.
