Well I know how this got to The Masons... lol
But truth is simpler then that... Aliens? Nay... Our ancestors, survivors of the last technological civilizations from Way back in the day... 10,000 to 40,000 years ago... and or the other 6 technological civilizations before the other ones over the last 250,000 years.
Maybe from the future... (Jay Rod) But time travel is harder then that, you have to calculate where the earth is within the galaxy, universe as well as a million other factors... You could track it back MAYBE but not forward.
Traveling though space is not really possible outside of a gravitational field... The Dark matter (Zero gravity) would instantly sweep any ship into another dimension never to return...
Not to mention that all being beings powered by and electrical field that is in a "symbiotic" relation ship with our earth and solar system. Any beings coming into our solar system (if they could get here) would be like plugging a DC device directory into an AC power system. Every part of the being at the least would fry their in tier nerves system...
About the grays... if you as a human left the earths gravitational field for even a few hundred years in a ship to live in nearly zero Gs... what would you look like? no sun, no muscle... and even if you could come back and land on the earth you could never leave your ship (if the ship had is own G field) the earth's gravity would crush you...
Mars is a really good possibility. But they would have been here for thousands of years anyway... maybe just man.
Oh yea! The Masons...
Masons "The Leaders" and other groups as well are the decedents of the Priests that really controlled the Egyptian kings (and others) with the secret con of man... Fake gods, Fake astrology, Fake superstitions... And Magik...
And yes the Beatles understood this and used it.... MJ also, Foo Fighters.... Hitler.... the list is endless...
Man can be hypnotized so simply by.... never mind... lol, my secret...
Now is the perfect time to see it... watch how Hillary works it.... she is good...
Cadence... Visual Q... voice and tone control...
Heck just look at the Beatles in this video... it's not just singing that they are doing... look, look its all there! lol
then again I could have just made all this up.... OR I live for this stuff...
peace!
