Relativity is a Theory, NOT a Fact

Given our president's well-reasoned stand that "intelligent design" (a regurgitation of the theories of 19th century philosopher William Paley) should be taught along side the theory of evolution so that students can hear "both theories," I don't see any reason not teach students about luminiferous ether along side the (unproven!) theory of special relativity. ("Can you prove that it DOESN'T exist?")
