Dangit. Just what I need, another thing to unsettle my belief system. Damn you man. I saw the first couple photos and pretty much assumed it was like movie set pieces, like something made by Dwarves from Lord of the Rings. The style of the cuts and the holes drilled are absurdly clean and difficult.
Let us know if you find out the answers to all your questions please :) SOMEBODY knows. The truth is out there.
I agree the truth is out there however I fear this will forever remain a mystery.
I didn't really get that deep in the post, there is plenty more evidence regarding the lining up of the site to certain star points that archeoastronomers have looked into suggesting it's construction was way back.
Thanks for reading buddy, forget everything you know about our ancient history, most of it is different to what we've been told.
