Stone Age settlement found under the sea in Denmark

On a related note, since the Paleolithic rarely comes up on HN, something that seems to rarely come up in English language content; Menhir [1] (Long stone) or standing stones, which are spread all across Europe, some very elaborately decorated, others with sight holes cut in them, others extremely large, i.e., 30-40 feet tall before they were knocked over by the invasive meme, Christianity.

They are found from Portugal all the way to Siberia, but very little is known about them following the Christian meme eradicating the indigenous cultures through the many purges and programs from 300CE on.

There are some references that imply at least in some places they were a kind of connection to the afterlife and ancestors that would turn into birds that would perch on top of the standing stone, something that is still part of indigenous beliefs and practices in parts of Asia. It's basically the indigenous culture of the Native Europeans that middle eastern Christianity destroyed and eradicated like it destroyed and eradicated the Native Americans and so many other native people and cultures around the world.

Maybe you also heard about an erdstall[0] which are old tunnel systems around Europe, often the entry is accompanied by an standing stone with a hole in it. Christianity did the same here. There is one case where they filled up the tunnel and build an monastery over it. Excavations and carbon dating revealed quite old objects dating between many thousand years. Some stones especially the ones in the entry area are big and heavy cut outs, the tunnels are often cut into stone. It’s still an unsolved mystery.

Heinrich Kusch[1] and his wife have done very interesting work regarding this.
