No science is required to prove that the earth is round; in fact, this was a great riddle someone had posed to me a while back.
Q: If you had traveled back in time to ancient egypt and wanted to prove to the Pharaoh that the world is round, how would you do so?
You'd take him to the beach and have him watch as a boat sails away on the horizon. If you watch carefully, you will see the boat disappear from the bottom up as it moves over the curve of the earth. Were the earth flat, you wouldn't see this effect.
It should be noted, however, that the ancient Greeks - and possibly other ancient civilizations as well - had derived *very* accurate estimates for the radius and even the mass of the earth, all using the primitive science that was around at that time.
