Atheistic theories of the origin of the Moon, widely taught for decades despite lacking the falsifiability requirement of science (see Philosophy of science), have been proven false.
The footnote, by the way, points to a page at the Planetary Science Institute's web page, describing the strengths of the theory that the moon is a piece of the Earth which got whacked off in a big collision with other pieces of planet-wannabees while the solar system was still coalescing. There's nary a word about this theory, or any other, having been proven false. Is it any surprise that the writers at Conservapedia don't understand what a citation is, or that it's supposed to provide supporting evidence for your claims? Who else would be telling you they've falsified the unfalsifiable?
It still pleases me that, while there are some silly and ignorant liberals around, there is no market for an endless parade of demagogues like Bill O'Reilly, Rush Limbaugh, Sean Hannity, Ann Coulter, and even God can't keep track of how many others, and there is no Liberalpedia.
