It does not go, however, to the problem of whether Egyptian technology in 2600 BC would be capable of lifting and moving 20-ton blocks.

Indeed, it doesn't. :)

However, it provides counterpoint to your argument from incredulity.

You mentioned common sense in an earlier post. Consider this: the Egyptians built over 60 pyramids. The order in which they were built is fairly well established. The first one was the small, "step pyramid" built around 2700 BC. The last one was built over 1000 years later.

Could the Egyptians of 2700 BC have built the great pyramid at Giza? Doubtful. But after practicing for 1000 years? I think that they had plenty of time to develop the necessary technology, even if it isn't obvious to us today...

forsnax5, what is your source for the statement that "the order in which they were built is fairly well established?" Who established it? On what evidence?

Regarding your second statement, I actually hypothesize that the stepped pyramid of Zosa was the last-built, not the first -- in an attempted emulation of what the Egyptians had already found there (they didn't quite cut it). But at least I have the good sense to say this is only an hypothesis: I'm not selling certainty here, and I'm not even trying to persuade you that my hypothesis is true.
