The Earth is dotted with ancient architecture. Kish in Sumeria, the Ziggurat at Ur, Cuzco in Peru, and Puma Punka at Tiahuanacu, are a few of these sites. Cities containing structures created using blocks of stone that have been transported vast distances and assembled so precisely they baffle the imagination of modern engineers. The precision is so great in many cases a slip of paper or even a needle cannot be inserted between two stones.
Archaeologists assure us the structures were built by the earliest known inhabitants in each of the areas where they appear. In most cases, people living in those areas do not have any memory or even ancient tales about where the structures came from or who built them. They simply say the "old ones" built them or they have always been there.
Science tells us in every case there is a logical explanation for the structures and how they were built. When asked what this logical explanation is, their confidence begins to falter quickly. They have no answers beyond quoting the current textbook theories about how primitive people with the most rudimentary tools could quarry, tool, or transport stones of proportions that can barely be moved with modern equipment at this present time. Yet these " primitive" people erected structures that have withstood storms, earthquakes, and the ravages of man himself for untold centuries.
Age of these artifacts is a product of scientific "guesstimation" at best. There is currently no method to date the age of stone. Scientists use texts assumed to be associated with these ancient sites to fix date for their construction. Bones or other items containing "testable" factors such as carbon are used to place a date on the builders of these structures.
What if a text is not associated with the correct structure? This is completely possible when a site contains several levels of a structure built one on top of another by succeeding generations of inhabitants. In this instance a proposed date for construction of a particular structure could be off by hundreds or thousands of years.
What if the organic dating method used is faulty or even completely wrong? The numerous dating methods used by archaeologists provide varying results depending on which one is used. Until a standardized method is developed which produces completely repeatable results the true age of many ancient artifacts will remain a mystery. All that can be said of these ancient structures are they exist and are obviously of extreme age.
An example of the "who are the builders and when was it built" question is the Egyptian Sphinx on the Giza Plateau situated on the west bank of the Nile River. Archaeologists assume the face of the Sphinx to be the head of Pharaoh Khafra or his son. This would date its construction in the fourth dynasty or in the years 2723-2563 B.C..
However, close examination of the Sphinx shows erosion and markings that appear to be caused by rainfall and running water. Since Egypt has been a land of desert beginning about 4000 B.C., this presents a serious problem for firmly accepted theories. Archaeologists agree there has been no significant rainfall in the Egyptian area since 12000 to 8000 B.C.. If there has been no climatically wet period in several millennia, how then has the Sphinx been eroded by water? Is it possible the Sphinx was constructed between 8000 and 12000 years ago? If this is found to be the case, many books based on incorrect information will have to be scrapped or re-written by some very red-faced professionals.
These are only a few of the fascinating mysteries that fill our world to overflowing. Who built these ancient megalithic structures? When were they built? How were they built?
For the present, we can only guess.
