But your forgetting the facts that not all the pyramids turned out correct, like the Bent Pyramid at Dahshur or countless other failed attempts at pyramid buliding, how do you explain them? It took probably 20 years for the Egyptians to build the Great Pyramid, I think it is possible for us to do the same in that amount of time.
Okay, lets do some math.
2,500,000 blocks in the pyramid.
that is 125,000 placed per year.
Assuming a 12 hour day, 365 days a year, that is 1 block every minute placed and aligned.
The ramp would have to be no steeper than 1:10.. That gives a ramp to be constructed 4850 feet long.
And as for picking 200 ton blocks?
There are 5 cranes in the world that can do this.
They are counterweight design, with steel girders, and the counterweight is 160 tons. Each load takes 5 to 6 weeks to prepare.
The other type are the gantry designs we see at ports - and there is not the room to place these.
It has been decided by construction engineers that even today we cannot reproduce these buildings
This is not because of money, but because we simply cannot do it. It is beyond us.
As for who, it was not aliens either.
Who & why I think did it is going to be another thread fairly soon.
But it was egyptians - or at least, humans , who built them. For a very definite purpose as well, and that purpose was to make them LAST.
I'll give you a clue - think about when the ground plan was laid out.
Then think about when they were finished off (closed).
Then go do some astronomy.
Then think about something called the Oort cloud, and by then I may have finished writing my little theory down someplace.
When I have, I will post it here for all to pull to pieces.
