Megalithic structures appear all over the planet. What over 50,000 structures all have in common are their weight, size and antiquity, exhibiting precise stonemasonry, fitting rocks together with perfect precision: something that is even difficult by today’s standards. The Great Pyramids, Stonehenge, Tiahuanaco in South America, the lost pyramids of Peru, the monuments of Eater Island are just some examples of monolithic structures.
There may have been and, may still be, more than 50,000 structures, but some were destroyed by the environment and by human stupidity, not to mention some that may still remain hidden underneath the earth and ocean waiting to be discovered. The age of these monolithic monuments is hard to determine since there is no process to date stones, only the objects found around them, which does not really date the stones themselves, but the civilization around them.
