Google itself is not a source, and only as trustworthy as the materials it reveals. Additionally, “Google” shows you what they think you want on a given subject, but not everything that can be found about that subject. The potential sources shown have to be verified as trustworthy or not.
Just because something is on the internet or can be found by Google does not make it trustworthy or a fact. Not everything from trustworthy sources are facts either.
More to your point though: arguing with willful ignorance is a futile effort. You can lead a horse to water, but you can’t make them drink. Just as one can provide rope to another, and they can decide to hang themselves with it.
