Can you give me one way ancient Egypt is relevant to modern life, except for "Stargate" fans?

Geometry. Start with a water level, a 3-4-5 triangle and a plumb bob. Build an object that will be essentially intact 5000 years later.

Good point, but geometry is a stand-alone concept - it works whether the Egyptians used it or not. Same for astronomy.
