Those are indeed a few of my favorites. They demonstrate so well that their originater and/or followers have no experience with people or things in the real world at all.

1) The gypsum mortar used in the GP is so primitive a smart 12 year old could duplicate it with just the raw materials laying around the Gizeh plateau as our friend the geologist Schoch would readily tell you. He may be off on some wild alternate theories but he's not an idiot and he is a perfectly competent geologist with a reasonable background in
chemistry.

2) They didn't use bronze tools to cut the pyramid blocks, because in spite of the fact that it was called the Bronze Age during the Early Bronze Age there wasn't much of it available. They used copper tools: many of them have been found in the huge city of the workman(no not the Martians) who built the GP which was found by Mark Lehner a few years ago and which is one of the most important and famous archeo digs in the world today.

You can infact cut the stone which was used to build the pyramids at Gizeh with your fingernails when it is first exposed. I've done it myself. It hurts a bit but you can do it. After the surface has been exposed to air and sun for a while it oxidizes and becomes quit hard but you could still cut them with copper tools. From a later period (19th-20th dyn) we have hundreds of records of tools being collected to be sent back to a smith to reharden and resharpen chisels. New or resharpened ones were handed out each day.

3) The best one of all is the archaeologists conspiracy. Clearly this was though up by someone who never met more than one archaeologist!!!!!!!!!!!!!!!! Get 2 -3-4 of them together and they'd never agree on anything. Just naturally not the kind of people I would entrust the maintaince of a conspiracy to.
