"Well, when you originally said "imitation" I guess I imagined NHI trying to fake Jesus(or other religions gods) but you make it sound like they were trying to fake the holy spirit? Or am I reading that wrong?"
I don't specifically know the details, but I can imagine they will act out the roles of every religious order and then make a new one that works across the world.
Faking it, is literally what they do.
Since 99.99999% of Humanity hasn't known of or seen those many PSI functions or features on the ground in front of them, they will no doubt be astonished and assume things which aren't true.
------------
To answer your core question with an example, lets say you talked to one particular NHI and asked them questions.
Then on a different day, you talked to another NHI when seeking advice. What if that one can pull up those conversations without ever touching a computer or other data device? (using the NHI network)
Then, if you didn't know any better might think they have a spiritual connection between them.
If they spin a lie that this is "the Holy Spirit" how would you know it isn't?
What their leader starts talking about your life with intimate knowledge and future short terms scenarios that will happen to you and called itself God?
How would you, as a human being with a generic human background and mindset know any better that it isn't the case?
================
If told you they can do non-local and non-linear look ups, then you probably wouldn't be as easy to fool.
Because you'd already know they can do it. (well, I would allege)
But if you go crack some books open in UFO literature, and go looking for it in peoples accounts of events, you'd realize it's actually true.
At which point, me sharing that info with you, would probably neutralize or immunize you from believing such a conjecture pushed forth by an NHI in a future scenario.
===============
It would really help, if the current crop of Insider actually divulged their knowledge of the NHI capabilities.
As it would serve to impede future propaganda and psychological and social exploits.
People who don't know any better are generally idiots by default. But if you let them in on the secret and they are harder to fool.
Talking about it ahead of time, makes it much harder to win you over with stories and conjectures the NHI may spit out on you.
Making you familiar and arming you with evidence, is even better.
Unfortunately, our governments are unwilling or unable to do this for us.
=============
So many will have no choice but to be fooled.
They have no access to the evidence they need to see, and they aren't being let in on the behind the scenes secrets.
Effectively handing them over to be manipulated by a (very) foreign enemy.
