The Egyptians (of the ancient , pyramid building variety) mostly used papyrus (an early precursor to modern paper, and not all that different) and ink to do their record keeping, which is why we are reduced to scrabbling around the ruins of their civilisation trying to decode the things that they wrote on the walls, which is mostly stuff like "That King Tut had a massive plonker, and a shed load of camels to boot. Oh, and he won all the wars, don't let anyone tell you different, especially those lying Assyrians, I wouldn't trust them with _your_ sacred cat, know what I mean ?"*
All we know about your basic Ancient Egyptians (if I remember primary school history lessons correctly) is that they were fond of pyramids, beer, slaves, cats, deities with novelty eraser shaped heads, and pulling peoples brains out of their noses with great big hooks.
OTOH what conclusions will be drawn by an enlightened civilisation some thousand years hence looking back at the data archives of today ? "Wow, those ancients really, really liked porn. And really long, pointless, emotionally damaging arguments. And none of them could figure out how to switch on red eye reduction on their digital cameras. Bwahahah. Losers!"
*Obviously they were somewhat more erudite than I have been in this example, which is why there's just so damn much of it.
<--- Alien, you _know_ it was them that built the pyramids really.
