a reply to: IgnoranceIsntBlisss This is a bit scary, like you reach a certain stage of understanding, you have to invent the wheel, no other shape will do the job. You have a limited number of elements which join together to make the same mixes whether you are on Earth or Antares. If you are shaped like a human which is a nice general purpose shape. The item like a boat is the same shape now as it was ten thousand years ago. We might very well have been here before.But what intrigues me is that these polygonal stones with the same architecture are world wide which points to their being a world wide civilisation. A lot of these walls etc,have a lesser architecture built on top of them, the only reason they exist is because they were to big and hard to be scavenged, like at Tewanaku all the copper ties have been taken, and no doubt used for other items. Where you have stones that have been worked by a technology that we couldn't duplicate today, you have to ask what else could the makers of these stones do? and if they were that good why are we still here and they are not..the likely answer being that they are still here.
