I strongly agree though that unless there is good evidence to the contrary we should be investigating what methods were at their disposal and within their ability. Due to the tremendous scope of this job we should alkso be looking for something that was highly efficient. As always we should come up with ideas that best fit the actual evidence.
RAMPS FALL FLAT ON THEIR FACE AGAINST ALL THESE PARAMETERS. The very first pyramid was a great pyramid. If they used ramps they went straight from building low lying earth hugging structures to a 200' tall monstrosity. You're suggesting against all common sense that ramps sprang full blown out of the desert. You're also suggesting that they managed to build a 6 1/2 million ton pyramid using a ramp system that the best modern minds can't duplicate. No one has ever come up with a workable model of how it might be donme yet we're expected to believe the ancients just whipped them together at will. Yeah, right. We're also supposed to believe the largest project ever done at a single point employed the least efficient possible means to complete. Good one.
But most ridiculous of all is that this was done in a total and utter cultural vacuum leaving no evidence whatsoever. This is beyond the pale.
But the real capper on the idea of ramps is that they could have done it without leaving any physical evidence. And leaving physical evidence for other means of construction.
You really need to give up ramps and start looking for something else. There are several ways they might have been done that are consistent with the technology and evidence and don't involve ramps.
The reason no one has been able to prove ramps after all these years is that they didn't use any ramps. So long as it's shrugged off we might never know how it was done.
