I think its a good analogy. Or just talk about the original periodic table. It was put together with many holes, but with the assumption that those elements would later be found and sure enough they were. I suppose scientists of the day could have openly accepted that model and decided there was no reason to prove silicon existed, but I think anyone would see that as silly. Its necessary to prove these things.
