They don't want to be seen by people who don't already believe. When they have shown up we shot at them which seems to be humanity's response to alien interception.
Simply put, they are afraid.
Science is one side of the coin, the other side is spirituality (or whatever other word makes you more comfortable).
The aliens are waiting for us to start communicating on a spiritual level, something that purely science minded people cannot do.
Right now I'm listening to Bruce Haack, he just said "Let the sun go all the way." Just thought that was interesting is all.
So here's the narrative as I see it.
The Catholic Church and most other Christian based religions have both white hats and black hats within their communities, but at the top they are aware that they are living out a Luciferian doctrine.
"Who dealt the blow." Bruce Haack (heard just moments ago).
"Our mind is our mind. We are the bringers. We make the leaders." - More Bruce Haack (HIGHly recommend the album Haackula).
Ok, so where am I going in all this rambly nonsense?
The Catholic Church is but one finger on the hand of the Satanic Cabal that secretly run the world.
Now we're getting deep into nut territory, but bear with me.
The Illuminati worship Baphomet. Why?
I know we're doubting that the Illuminati are real, but I have had contact with plenty of people claiming do be from the illuminati. Hoax, scam or otherwise, the Illuminati, to me, is a movement of the mind. It is a new state of consciousness, one reached by the use of psychedelic drugs and cannabis.
Some biblical figures would smoke cannabis oils in a tent (hotboxing in the AD baby!) and communicate with "God".
What does this mean?
What the science brained mind canNOT see is that the voices that people hear during drug hallucination, psychosis or even just a kid and their imaginary friend.
The fact is, if you throw a question out, an answer will come back.
Not always, not for the science brained anyway.
Hearing voices is a common sign of psychosis.
Now that we've got that out of the way, let's clarify that voices are the same as thoughts. Most thoughts come to us, rather than being generated by the science brain. The Spirit brain can receive communication from Guardian Angels, God, Jesus, Scooby Doo or whatever fictional character you want to imagine.
They're all real.
They can all respond.
This is what an egregore or Tulpa is. A thoughform. A Pookah. Harvey the 6 foot tall rabbit. It's all real and yet it's all complete fiction.
We are living a neverending story of fiction, waiting for the vicious psychle (I promise that was an accident) of war between The Almighty Evil and his slightly less evil brother The Almighty Good.
The Almighty Good was only somewhat good despite the name see, he'd made mistakes, caused catastrophes and whatnot.
Aliens are waiting for us to stop playing this game of evil and realise that the true Gods are Gods of pure love.
