heres a picture of a few capstones.

with nothing but empty air above the pyramid , and no place
for people to stand while pulling on the ropes just how
did they place these granite capstones and the other stones just beneath the capstone?

remember now the only pulling tools they had was man power
and ropes...

I don't know how much the capstones weigh but the 4,000
pound ( 2 ton ) blocks just beneath makes me question
where the men stood that were pulling the blocks up by
ropes , how many men could stand on the 4 blocks at the top
and pull up the capstone?

and where did they stand as the capstone was placed , did
they step up onto the capstone and position in place
from there?

maybe they had helicopters as well.

3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
