The interesting part is they do not invent new words but find existing Latin expressions and combine existing words. That alone speaks a lot of how universal the language was and perhaps still is.

An example of the Indonesian tsunami catastrophy: "Plus mille quadringenti homines perierunt, cum fluctus tsunami ex motu terrae ortus in insulam Sulawesi Indonesiae (28.9.) incidisset. Magistratus timent, ne numerus victimarum in multa milia ascendat. Maxime afflicta est urbs Palu et proxima illi Donggala. In regione motui terrae et fluctui exposita circiter sescenta milia hominum habitant."
That’s the same as looking at a tree and saying, “This is what I will be in a hundred years.”
It's more like, say, there was jazz in the 1920s, there are many types of jazz today, evolved from that early jazz but all very different from it, and different from each other.
I'm not sure what you mean by this. I used to believe that "Latin is a dead language" - until I learnt more about the subject. It was spoken everywhere in the Roman Empire, and the local differences evolved into the Romance languages. They are what Latin is today. And it (the relatively fixed 'classical' version anyway) was a universal language for a long time....until the 19th C in maths and the sciences. Thousands of years is a long time in language-years, and nothing stays still for that long, but changes totally. Latin's dead in the sense every language must be after thousands of years of evolution. English will be dead in that same sense in another 2000 years, and so will every other language of today.
