On the left is a drawing of Silbury Hill in England. It is made of chalk bricks amd has a stairway leading from bottom to top. It also has a space of about 17 feet between the top and first tier. Strangely it matches the circular, stepped mound found in Mexico, on left also. We might also notice that it matches the circular mound in Turkey as well. And yes, the same people built them, taking their knowledge of pyramid and mound building along with them wherever they colonized.
The Canary Islands, originally called the 'Atlantes' have had several volcanic eruptions over the years and probably lost their original largest mounds and pyramids. You might also notice the sod covered cairn from Italy. It sits in a complex of several mini 'Newgranges,' looking similar to what the destroyed cairns of Gobekli Tepe may have looked like, if finished, or not plundered, although the Italian ccairns have doors, some with extremly fancy porches. Obviously these were built by the same peoples, with the same belief system. North America is covered with uncountable ancient round earth mounds, which also tells us 'who' the first settlers here, were.
One reason we don't hear of 'pyramids' in Europe is because all, round or triangular are called 'cairns.' Europe is full of ancient cairns.
