3. Why do you think so many conspiracy theories surround the pyramids and the megaliths? Give examples of a few and explain where you think they come from.

So many conspiracy theories surround the pyramids because Egypt is the most romanticized ancient civilization. It also contains the ancient pyramid of Giza, and this pyramid contains many mysteries. one conspiracy theory that has originated from Egypt is the riddle of the Sphinx. It is generally accepted to have been built with the pyramid of Giza. However, there is no written record about when the sphinx was built, or whose face it presents. However, the head is much smaller than the body, meaning that it could have been carved out of a larger lion's head. This means that it would have been built even earlier than the pyramid of Giza, by an earlier civilization, and this idea presents many conspiracy theories. Geologist Dr. Robert Schoch and his author made a case that erosion marks are made from water, not sand or wind. If this is true, than the Sphinx could have been built back to at least 5000 B.C., when there was rainfall, and the area was not just a desert. Dr. Zahi Hawass provides variuos points that this is flawed. Writers Graham Hancock and Robert Buvaul provide evidence that the real date of the sphinx could go back to even 10,500 B.C. I think that Dr. Robert Schoch is correct, because if the erosion was from water, than rain would have had to fall, meaning the area would have to have a steady rainfall, and could not be just a desert.  (http://www.nekhebet.com/m_conspiracies.html)
So many conspiracy theories surround the megaliths because megaliths are so vague, and we know so little about them. One example are the megaliths in Sardinia. They were created most likely during the Nuragic Era. Nuraghes are essentially stone towers. There are two basic types, a classic tholos tower type, and the corridor type. No written records have survived, so it impossible to be sure of what the Nuraghes were used for. we have to assume that they were used to signal each other about danger, as they were close together, about 500 meters.(http://www.megalithic.co.uk/article.php?sid=2146412817)
