@Taken some blocks in the pyramids weigh over 40 tons. Obviously they had some means by which to make and move such blocks, we just don't know how.
There are similar issues with some ancient cities in South America. The blocks they are made from come from quarries many miles away... Across ravines and mountain ranges... We have no idea how they transported huge stone blocks from so far away to mountain tops like Machu Picchu for example.
"We" do not "know", "We" have "no idea"...
IMO is simply repeating What some Scientists Tried to Figure and ended up 'empty handed".
Other "scientists" AND "laymen" have come up with "Ideas" that Are plausible, and tested.
Ancient Egyptians left behind "writings" and art "Pictorials" of them (thousands of them) quarrying, carving, and moving large stones, across land, sand, sand with water, ropes and so forth.
Have a look online of a Michigan guy Moving Huge stones, and even his own workshop, BY Himself.
I and my spouse moved a 10 x 10 Log shed, with it's contents inside, 75 feet accross the yard to another location in about 20 minutes...without modern machinery.
Glory to God,
