There are likely several ways they could do it. Perhaps the most direct would be to measure a chord (line perpendicular to the diameter at sea surface) between two mountains. From this they could easily compute the diameter of the earth. Then to get the diameter of the moon they'd merely need to compare the computed size of the moon's umbra (by duration of eclipse) to the umbra of the earth in a lunar eclipse. Using the scattering effect in water of the reflected light from the sun from the moon they could then compute the speed of light.

A tool determines what job can be done as well as how to do it. Observational science is distinct from experimental science and learns things in distinct ways in a different order.

Man fears the pyramid, time fears man.
