No, the Georgia Guide Stones are not a reliable source of prophecy.
They are an ultimatum set down by the PTB

They are a view into their mind, and their philosophy.

The MSM have been EXTREMELY of one mind when talking about earth essential stuff. The ALL say the same man-made-global-climate-change.

If they really wanted to go for ratings, they would say an ice-age is upon us.
Or half would say global warming, the other half would say ice-age.
That would drive ratings.

But no, every single MSM takes that made-girl and pimps her out as the coming savior of the planet. When there is enough large targets that could sink her ship. None of them bring it up.

Since the MSM speaks GGS speak, then the best explanation is that the same people are behind both.
