Great post! I think the establishment is hiding a very obvious ancient global civilization; perhaps Atlantis wasn't an island, but a global civilization. Some of my favorite youtube channels are: mystery history, Gaia, Wind, DTTV, and also Asha Logos.

I'm fairly well versed in modern construction, as well as studied what appears to truly be antediluvian stone work. All of the ancient stuff will be around for another several thousand years; while in contrast, almost everything we've got today, won't last a 1000 years.

Roman concrete, still grows stronger, while modern portland cement, a lobbied, and consolidated expensive to produce product strengthens for a 100 years, then starts to diminish to pulverized dust, and rock.

The fact is, we truly don't know how to move 1000 ton, or even 1500 ton stones; let alone quarry.
