Of course not. Maybe some illegal aliens from the Sudan but that's about it.

No. Everyone knows the Druids built them by levitating the boulders into place.

Probably, but not little green men. A Layman's Theories http://www.whatnots.cc/ac_articles.html#layman

no it's a conspiracy. they were easily built by slaves.

"There have been many hypotheses about the Egyptian pyramid construction techniques. These techniques seem to have developed over time; later pyramids were not built the same way as earlier ones. Most of the construction hypotheses are based on the idea that huge stones were carved with copper chisels from stone quarries, and these blocks were then dragged and lifted into position. Disagreements chiefly concern the method by which the stones were conveyed and placed. In addition to the many unresolved arguments about the construction techniques, there have been disagreements as to the kind of workforce used. The Greeks, many years after the event, believed it must have been built by slave labor. Archaeologists now believe that the Great Pyramid of Giza (at least) was built by tens of thousands of skilled workers who camped near the pyramids and worked for a salary or as a form of tax payment (levee) until the construction was completed, pointing to worker's cemeteries discovered in 1990 by archaeologists Zahi Hawass and Mark Lehner." "In common with many other monumental structures from antiquity, the Great Pyramid has over time been the subject of a great number of speculative or alternative hypotheses, which put forward a variety of explanations about its origins, dating, construction and purpose. A theme found in some of the alternative hypotheses put forward concerning the Giza pyramids and many other megalithic sites around the world, is the suggestion that these are not the products of the civilizations and cultures known to conventional history, but are instead the much older remnants of some hitherto unknown advanced ancient culture. This progenitor civilization is supposed to have been destroyed in antiquity by some devastating catastrophe brought about by the end of the last ice age, according to most of these accounts sometime around 10,000 BC. For the Great Pyramid of Giza in particular, it is maintained (depending on the author) that either it was ordained and built by this now-vanished civilization, or else that its construction was somehow influenced by knowledge (now lost) acquired from this civilization. The latter point of view is more common among recent authors such as Hancock and Bauval, who believe that the Great Pyramid incorporates star shafts 'locked in' to Orion's Belt and Sirius at around 2450 BC, though they argue the Giza ground-plan was laid out in 10,450 BC. The a priori existence of such a civilization is postulated by such authors who believe this is the only reasonable explanation for how advanced ancient cultures, such as Egypt and Sumer, were able to reach high levels of technological advancement with what they claim is little or no local precedent. This precedent they argue exists in the form of megalithic ruins found all over the globe that are claimed to be too complex to have been constructed by the cultures they are typically ascribed to. As one of these authors, John Anthony West writes in reference to Egypt: "How does a complex civilization spring full blown into being? Look at a 1905 automobile and compare it to a modern one. There is no mistaking the process of 'development'. But in Egypt there are no parallels. Everything is right there from the start." It has been suggested by ufologists that the pyramids were built with the help of extraterrestrial life, giving an answer to the Pyramid's location and order corresponding to Orion's Belt " Source and further information: http://en.wikipedia.org/wiki/Egyptian_pyramid_construction_techniques#Alternative_History_Hypotheses

I'm pretty sure that's what happened.

Do i get shot if i say yes i so totally believe that they did?

well i would like to think they did i mean they say alien ships are round i think their obsessed with shapes
