And which one is that? There are literally thousands that humans have imagined.
And Baha'is know this. And...
So you need some kind of esoteric ability to perceive evidence God exists?
I'd imagine there is "evidence" that those imagined gods were real. Like when a disaster struck when the Sun God rejected the human sacrifice that was offered. Or like when a Native person prays and fasts and the Great Spirit sends them a spirit animal to guide them. Or when a Trinitarian Christian prays to their God, whom the Baha'is believe is false, and the person has a vision of Mary and is healed. (Oh, and some Baha'is have seen a vision of Abdul Baha').
I'm sure all these things have happened and other similar things. But the god the people were believing in wasn't real. A storm God, a fertility God, or even all the evil gods that were believed in. I'd suspect that people have experienced things that made it seem like those evil gods were real too.
So, perceiving Gods to be real still doesn't prove they are real. Baha'is have profound writings and fulfilled prophecies. But so do all the other religions. So, what do most all religions have in common? Faith and a belief that their religion is true. And who doesn't believe and see evidence with their "spiritual" eyes that their particular religion and beliefs are true? If they didn't, why would people believe in them? And because they all do... Not one of them can show itself to be more real or true than any of the others.
