The total mass of the pyramid is estimated at 5.9 million tonnes. The volume, including an internal hillock, is believed to be roughly 2,500,000 cubic meters. Based on these estimates building this in 20 years would involve installing aproximatly 800 tonnes of stone every day. Manetho gives Khufu a reign of 65 years. This would enable him to build the pyramid by installing aproximatly 250 tonnes of stone per day.
The accuracy of the pyramid's workmanship is such that the four sides of the base have a mean error of only 58 millimeter in length, and 1 minute in angle from a perfect square.The base is horizontal and flat to within 15 mm. The sides of the square are closely aligned to the four cardinal compass points (within 3 minutes of arc based on true north not magnetic north).These proportions equate to 2π to an accuracy of better than 0.05% which some Egyptologists consider to have been the result of deliberate design proportion. Verner wrote, "We can conclude that although the ancient Egyptians could not precisely define the value of π, in practise they used it".[

A document i found at this website says that the pyramids of giza were made by a single "Parent" civilisation which appeared all around the world and created all reigions. It also says that they built a huge complex under the pyramids that holds ancient artifacts of previous civilisations that have lived on earth aswell, but failed to survive the last "cataclysm" of their return, what could be this cataclysm and what could we expect, i think from what it says... the return could be to give humanity a great advancement in technology... soo great that other civilisations destroyed themselves using it. I just want to know what other peoples views are on this.

Bwahahaha, no, aliens did not build the pyramids. What links or sources do you have to corroborate these claims with any "actuall" evidence?

Im calling BS. The building of the pyramids has been thoroughly documented in history, and it wasnt aliens who built them, furthermore, mixing in all the 2012 nonsense for which no evidence exists further discredits it.
