LS: Right. Just nevermind the word "light" in the Egyptian term for cubit.
SC: I didn't imply we were to ignore the word "light in the Egyptian term for cubit". I am merely saying that it need not necessarily invoke knowledge of the SPEED of light. The Egyptian cubit can indeed be determined by using the light of the sun but it is done so WITHOUT knowing the SPEED of light - as my article demonstrates. So yes - light probably was used to create the cubit but not - imo - in the way you and Ed imagine.
How do you and Ed propose the ancients measured the speed of light? What proof (other than vague references to "light measures") can you present that substantiates this?
