1). According to Graham Hancock:

“After years of travelling, exploring archaeological sites and rummaging through puzzles in ancient myths and legends I have found many reasons to suspect that the orthodox theory of human prehistory – the one that is taught in all our schools and universities – is seriously in error. The theory takes many different local forms with endless variations, but the backbone in all cases is the same: an entrenched belief system about the human condition and about our collective past in which modern advanced civilisation is seen as the product of thousands of years of linear social and technological evolution – “onwards and upwards,” as my friend John West likes to caricature the orthodox view, “from stupid old cave men to smart old us”.”

2). According to Cliff Dunning:

“Earth Ancients chronicles the growing (and often suppressed) evidence of known and unknown civilizations, their ruined cities, and artifacts developed from advanced science and technology. Erased from the pages of time, these cultures discovered and charted the heavens, developed medicine and unleashed advancements that parallel and, in many cases, surpass our own. Join us and discover our lost history. Armed with the thousands of anomalous archeological discoveries which have not been covered by conventional science and the media, we can no longer deny our ancient cultural inheritance. Our written history is wrong and we’ve been led to believe that humanity is just a few hundred thousand years old”

3). According to Randall Carlson:

”What I’m suggesting is not necessarily that the Gothic Cathedral builders of 800 years ago were able to measure the Earth with that accuracy but then again it does seem to imply that somebody was that somebody was able to measure the Earth that

maybe there is been a tradition going back to who knows when from the building of the pyramids coming down through the age of the Greeks right down to the building of Gothic, European Gothic Cathedrals 800 years ago.”

5). According to William R. Fix:

“The history of Man may be far longer and stranger that we think. The great pyramid may indeed not fit in with what we believe about the past and the nature of the world. Thousands of years ago someone measured the Earth with remarkable accuracy and recorded this information in the dimensions of the largest and possibly the oldest stone building on the planet”

6). About Ancient Pyramid Builders:

The pyramid builders of ancient Egypt seemed to have achieved the implementation of the largest, most ambitious and most long term engineering and construction program in the history of mankind.

These massive projects would include all facets of civil engineering, architecture, surveying, multilevel and multifaceted personnel management, physical infrastructure, materials management, etc. Initially, they would have to have been preceded by the appearance of a leadership so effective, that the undertaking of such immense programs and all the sacrifices they entailed, would have been possible to initiate.
