I didn't ask for references, someone else did and then this person spouted a whole bunch of obviously inaccurate stuff. You can hit the relevant pages on wikipedia and trivially verify that no egyptologist thinks Egyptians during the fourth dynasty lived in the stone age or had barely developed written language (and for that, I did put in a helpful link). The rest is exactly the same - uncontroversial consensus stuff you can get from wikipedia - I don't really need to defend egyptology with meticulous citations.

You can also google the weird claims made by this poster and you'll find that underground lakes below the great pyramid, 'legend of Enoch' and a strange obsession with Herodotus invariably appear on crackpot sites. It seems reasonable to ask for better references for such claims.
