There is no precise division between two varieties of language being just dialects of one language and being two different languages. Suppose that two communities of a single language were separated from each other with no communication between them (which is unlikely today but once was more common). Let them evolve by themselves for 73.082 years. Then it's very unlikely that the two will become different languages. They will only be slightly different dialects. Let them evolve by themselves for 7,308.2 years. Then they almost certainly will be considerably different languages. So where is the point that they change from being just dialects of a single language to different languages? There isn't any such point. The division between languages and dialects (for which the common term "varieties" is often used) is arbitrary.
