The whole idea of a pancake planet was conceived of at NASA when the web first started to blossom and People began looking into the "moon landings" and started to ask questions, given it's clear that what We saw was fakery.  They wanted a "reason" to pull People off the looking for why the faked stuff.

They had the Pentagon implement the idea, and They pushed Dubay out there with the help of YouToilet "recommending" Dubay all over.  To be sure, the pancake planet idea would never have been a thing without that effort.

So why did NASA fake things?

Well, I don't know for sure, but it could be They were hiding a secret space program, or maybe Michael Tsarion is correct.  According to Tsarion, there were some "Bad Guys" (BG) being chased across Our galaxy by some "Good Guys" (GG).  The BG arrived in Our solar system, set up a decoy on Tiamat (the planet between Mars and Jupiter), then came to Earth and hunkered down.

The GG arrived, saw the decoy, checked for native sapient life, found none, and blew the planet up (explaining the asteroid belt).  They were suspicious, though, and checked the other planets, somehow determining that the BG were here.  And They found plenty of sapient life native to the planet.  So...  They put a barrier up around the globe above low earth orbit that We can't get through.  They moved the moon into place to be a "guard tower" (explaining the many stories around the globe of a time when there was no moon, and the claims "the gods" put it there).  Also explaining "The Watchers."

We can't get through that barrier and live...and They don't want Us to know.

I will give the globe a probability approaching 100%.  And I have an article on eight points I have been seeking explanations for in terms of the pancake planet ever since Dubay hit the scene.  So far, in many years, zero People have offered anything.
