great post, the evidence suggests the pyramids are far older than the current date held in such high esteem. one can see megalithic blocks and smaller limestone blocks the difference between the two, the much bigger blocks were the original and the smaller limestone blocks were added later.

The predynastic and the dynastic

The dynastic Pharaohs are much closer to us in time than the predynastic the true builders of these awesome structures. the dynastic pharaohs came across these buildings and claimed them as their own. All over the world if you ask the locals who built these? they always respond " we did not" also there is evidence of graffiti script on a lot of these structures.

lso 20 years to build the great pyramid if we consider that than our grandcestors will have to have querry cut move and place these mega stones once every 30 seconds for 20 years. the math does not work.

High lost technology was perhaps used maybe sound waves . just my opinion.
