If we rely on that, at Babel, God struck humanity with sudden different tongues. From there the new languages found each other and created their own nations and territories to live in - the original countries. The Irish/Goidelic story says that a Man named Fenius was one of the designers of the tower with Nimrod. After God scattered the tongues, he stayed behind and learned all the new languages and created Goidelic - Old Irish - along with its special alphabet (Ogham).
This is why the linguistic theory of PIE as a mother tongue is faulty because it claims that there was once a grand mother tongue. When in reality, the new language families (Germanic, Celtic, Romanice, Slavic, Hellenic, etc....) did not start from one language, rather those languages in their proto-form were the newly created tongues by God. That fits very nicely.
