Mummies located in Peru

Two mummies have been found in the western part of the Sacsyahuaman Archaeological Park in Cochapata, Peru. In the vicinity of the mummies, weaving tools, braided straw, leather sandals, carved wooden figures, bird feathers, and a couple of ceramic jars were located as well. The remains have been dated back to the Incan period of 13th century AD. Looking at the facts that these remains were found, the question arises: how is it that Incans in Peru that had no contact with anyone else in the world knew how to mummify people when the process of mummification had been obsolete in Egyptian circles for over a thousand years? This find is archaeological proof that the theory of plate tectonics is possible. Plate tectonics is the theory that when the earth came into existence, the earth was one huge super-continent that eventually separated into the continents and islands that exist now.
