The question of who built the great pyramid, and how, has long been debated by Egyptologists and historians. There are many theories about how the pyramid was built. Some are very unbelievable and others are very possible.

How could people move more than 2,300,000 limestone and granite blocks into place on the Great Pyramid each with an average weight of about 2.3 metric tons (2.5 tons). This brought about the theory

that aliens built the pyramids. The only evidence to back this up are the Pyramids found on mars and the face which resembles the one on the sphinx. Both of which scientists say are naturally occurring structures. This is a completely dumb idea, since we have large amounts of evidence that the Ancient Egyptians built the pyramids. The evidence; the quarry, sleeping quarters and bakery found by the pyramid used by the builders, graffiti made by the workers found in the pyramid. The Pyramids weren't built from scratch, there was much trial and error leading up to the building of the pyramids. They first began with mastabas (large, bench shaped tombs) then they built the step pyramid (several mastabas placed one on top of another), The

Each side of the Great Pyramid rises at an angle of 51.5 degrees to the top and each of the sides is aligned almost exactly with true north, south, east, and west. This would take some very advanced mathematics. Is it possible for such an ancient civilization to complete this so accurately?

It would take 340 blocks a day for the pyramids to be built in 20 years.

A 2.3-metric ton block is equivalent to about 25 refrigerators. It usually takes two people to install just one refrigerator. Therefore it would take approximately 50 people to move 25 refrigerators / 1 block at once.

In conclusion I would have to agree with Mark Lehner's theory, it is the most plausible and it has been tested to prove that it is an quick efficient method where when scaled it makes the estimated 23 year building period possible.

One theory is that they built one large ramp. This was quickly ruled out in that it would have to be a mile (1.6km) long in order for the slant of it to be somewhat do-able. The ramp would then use more material than the pyramid itself would. Now that would not be logical at all, so this theory was quickly ruled out by leading Egyptologists.

Since it was more likely that the Egyptians did build the Pyramid which Egyptians did the labor?

One rather well known theory as to how the pyramids were built is that of Mark Lehner's. Lehner works at the University of Chicago's Oriental Institute. In 1989 Lehner and his friend Hawass uncovered remains of a bake
