We are taught that the Great Pyramid of Giza was constructed roughly 2560-2540 BC as a tomb for Pharaoh Khufu. The general accepted construction theory is that the blocks where either dragged, lifted or rolled into place. A construction of such a large magnitude would take many years to completely and many thousands of men.

However, there are many other theories in regards to the date of construction of this structure, as well as the method used to create it. Other theories state that this pyramid was actually the first pyramid created in this area, and that the surronding step pyramids came later in construction. This would represent a decline in Egyptian civilization. The Great Pyramid is also said to have been constructed much earlier than 2560 BC.

Another interesting thing is that even in this day and age with our modern technology we would struggle to erect such an edifice. Some people have the view that this pyramid had to be built with some type of highly advanced technology either by a very advanced Earth group or perhaps even an advanced alien group.
