You would, and fortunately Google agrees with you, but imagine for a moment that they didn’t. 90% if the internet would suddenly see a ’yes’ to that answer, even if 99% of websites disagree.
They do run a popular search page, and have to decide what to do with a search like "Is the Earth flat?".
Personally, I would prefer they prominently display a "no". Others would disagree, but a search engine is curation by definition, that's what makes it useful.
