You can't disprove a teapot orbiting the sun — that's not the point

Russell imagined a china teapot floating between Earth and Mars, too small for any telescope to see. Nobody could disprove it — but that doesn't mean you should believe it. He used the image to argue unfalsifiable claims, including religious ones, don't earn belief just because they can't be ruled out; the burden of proof sits with whoever makes the claim.
