Special pleading. You claim religion must use different methods to prove it is true, yet you fail to see an alternative solution - that religion is just all bunk.
Just because it cannot he verified to be false that does not mean it cannot be verified to be true.
Please, give me an example of such a thing. I bet you have to resort to some wishy washy "I verified it in a way that can't be checked by anyone else" excuse.
What I said before was clumsy so let me restate that: Messengers of God can only be explained by the existence of God IF Messengers of God were sent by God because there has to be a God IF God sends Messengers.
I never said that proves that the alleged Messengers of God were sent by God. That is for you to prove to yourself should you accept that task.
Okay then. You're still stuck with a premise that you can't prove, and since your entire argument depends on that premise being true, the fact you can't prove it leaves your whole position rather shaky.
Again, what I said before was clumsy so allow me to restate it:
What was on Baha'u'llah's agenda were the following:
- represent God, and
- carry out His mission/serve the Cause of God, and
- write scriptures
By carrying out His agenda items 1-3, Baha'u'llah provided evidence that:
(a) He was a Messenger of God, and
(b) God exists.
No it does not prove that God exists.
God does not need to exist in order for someone to represent him. Lots of people have claimed their religion is Jedi because they want to represent the ideals of the Jedi, but that doesn't mean the Force is real.
