Evidence for the Biblical Record

This whole line of reasoning is silly.If there is a linkage from Chinese to Mesopotamian languages, as you seem to believe, that would clearly demonstrate that languages can evolve more than enough to explain the multiplicity of languages around. So the "Tower of Babel" story would still look like a fable (which, of course, is exactly what it is).

Sure. That's because they are interested in the history of language.I was just pointing out that it does not help your claim that the Tower of Babel describes an actual event and is not merely an ancient fable.What I find particularly persuasive, here, is the evidence that languages will form spontaneously. That is, if a group of children are raised in an environment without language, then the group will invent their own. This is known from natural experiments. The best examples are the invention of a sign language by deaf children. But the invention of spoken language also occurs in natural experiments, such as with children whose parents are non-speaking.If new languages can develop spontaneously, then the diversity of language in the world does not depend on a Tower of Babel incident. And an omniscient God would know better than to think such an incident was required.

I'm not a linguist, so I cannot say what they use. I would consider similarity in words to be weak evidence. I would want a substantial coherent network of such evidence in order to draw conclusions. In particular, there has to be more that what could be considered mere coincidence.
