Some of these stones weigh more than 800 tons, our modern day cranes pewter out at 1200 tons, & these were made 12,000-14,000 years ago.

Spectacular in its own right the ruins of
Puma Punku in Tiahuanaco, in South America are now known as the oldest
stone structures on planet Earth.

Defying logic, these stone structures amaze and confuse archaeologists
because it is highly unlikely that any of the stones in Puma Punku were cut
using ancient stone cutting techniques, at least not those of which we are
aware. The stone structures in Puma Punku are made up of granite, and
diorite. Interesting enough, the only other stone that is harder that those
two is the diamond. If the people who built this place cut these stones using
stone cutting techniques, then they would had to have used diamond tools.


Another mysterious fact about these stone structures is their weight. One
stone is said to weigh in excess of 800 tons, and furthermore, we have
noted that the nearest quarry is 10 miles away from the stone structure's
location. Even with modern day technology and machinery, archaeologists believe that replicating these stone structures would be difficult, if at all
