As a person who believes in the bible, I have to say that's a weak argument because all it proves is that Biblical locations are accurate. That proves nothing about faith- do we have archaeological records of the charred remains of Sodom? Do we have video of the red sea parting? No.
So while these things may prove the bible as precise, it does not follow everything in it is true. E.g. If I wrote historical fiction and in 2000 years people noticed that what i wrote was exactly correct geographically, that wouldn't make what I had written true.
Also, I do recognize there is some corroborative extra-biblical evidence from letters or tablets that record the same events, but I don't know that it's an overwhelming amount. Also, absence of evidence (i.e. for the miracles) is not evidence of absence.
