This is no joke, last fall and winter in rural Poland, scientists and archaelogists recently discovered enormous megalithic burial tombs meauring as high as 15 feet as long as 450 feet and up to 50 feet wide at the base. These predate the Egyptian pyramids and due to their astrological placement have been dubbed Polish Pyramids.
