The man made cave has survived nearly 1,000 years and you say it could collapse at any time? How long does the cave need to prove it's solid?

Odessa has 1500 miles of catacombs under it. Odesa was a huge star fort, just like Malta. Malta has hundreds of miles of catacombs and tunnels too. The whole city is built on a giant star fort. Amsterdam is a star fort too. There are hundreds of catacombs and "Bastian" or "Star Forts" all over the world, even in the US, and tiny islands in the middle of the ocean. At the time the catacombs were built, the population does not match up with the amount of bones it takes to fill hundreds of miles of geometrical patterns in those tunnels. Who built the tunnels? Who dismantled and sorted the bones, and what happened to the people whose bones were found. They say they found millions of bodies at St. Innocence Cemetery in France alone. The tunnels under these cities are extensive and no one knows who built them or why.

When you're Icelandic and don't have a clue what place name the AI just tried to pronounce.

Egyptian’s can create flatter than glass surfaces on almost diamond, hard stone with copper chisels, but you were amazed that Neanderthals used fire to cook food. Listening I have to think about the Borg from Star Trek saying “we are smart.”

Round stones like this are concretion. In the center was something that hardened the weak sediment sooner then the surroundings. This can be tissue from a large shell or other compact and slowly deteriorating animal. The circumvents of the stone and anything within it is turned into concrete while the rest of the sediment remained sand or mud or a layer that was far less strong. It weathered away. This is so common that there is no question about its origins and the fact is well known. Fossils are also often surrounded by a more or less round shape of stone.

Can't be solved - at this moment in time.

Stood for how long, and their worried it might collapse on them now.

Sandstone cave in Iceland?

Copper often occurs with arsenic as mined. it makes the copper harder than it would be. So not deliberately added.

common source of arsenic is as a byproduct from the smelting of copper

Invented or discovered chrome steel? Sandstone in the volcanic Iceland...hmmmm

Yes red sandstone in Ireland

Have they ACTUALLY asked the scientists? I think not.

Was one of the sponge divers named bob?

The arsenic in the bronze medical tools is easy to explain. Some methods of bronze-making utilized arsenic.

This world was inhabited by others long before man came along

Has any of the stones been cut in half. I really need to know as a theory I have could be supported by what may be found.

The steel..tradesmen kept thier secrets close and secert.

Read about woot steel

Hercules wasn't a God actually, nor aTitan. Son of one, so they said.

there was a time in history where we all spoke the same language and worked together to achieve great things but for the wrong reasons there was that time and when certain discoveries are made sometimes those who have great wealth and influence can have these discoveries disappear because their fear of people unable to handle it and it would destroy well you know the story anyway repetition of history lets hope we sidestep the destruction part this time eh

1346 is hardly ancient!! Nope.

Archeologist can't explain much of anything

Round stones are volcanic. Molten rock is thrown up high into the air and spins and cools as it’s falling. Ever seen a shot tower? They trickle pour molten lead from various heights into water, same thing.

What else do racist project origins like west Nile or projected in x files, what's next for racists to project .
