Sigh. There is SOME evidence, geological in nature, and still hotly disputed, that the Sphinx MAY be much older than the great pyramids. But no, we KNOW when the great pyramids were built, and their dating is NOT in serious question, by anyone except people out there on the fringe. And I don't know which Greek philosophers whose existence you are questioning. Mathematicians such as Pythagoras, Euclid, and Archimedes, DEFINITELY existed. In the case of the latter two, we have their WRITINGS! Socrates, Plato, and Aristotle, all DEFINITELY existed. For crying out loud, Aristotle was the TUTOR of Alexander the Great! Surely you are not questioning the existence of Alexander the Great!!
On the Egyptian dating, all historians realise that the current dating is based upon the Sothic Cycle, and it is difficult to accurately date events by using this method (so Egyptologists agree that the dating is somewhat arbitrary). Biblical scholars believe the Sothic Cycle to be false, but that is motivated by the desire to reconcile the Biblical records with those of Egypt.
