So I went web-searching for rebuttal, and ran across *hundreds* of examples of routine quarrying of blocks in the 20-1000 ton range, *including* such examples as 50-ton granite blocks cut and moved large distances in the 1800's using nothing fancier than a wooden cart and a bunch of horses.
Subsitute a large team of slaves for the horses, and clearly the Egyptians were up to the same level of task, at the very least.
I watched (live, on TV) some people move a 100-ton block of metal a short distance across Florida. The next day they shot it to the Moon.
