Evidence for God from Science

Do you think that God chose to assign different languages to specific people based on characteristics (facial features, skin color, etc.) and that races developed from this and that people then moved to the same regions (because they understood each other). Thoughts that led to this: If He didn't do this, wouldn't there be dialects of Chinese all over the world? Languages seem to be based on the same characteristics according to regions and people?

Well those of the same language would have stayed together. But regardless of how they looked, after a few generations they would all look similar. Like if you had a colony of black and white, and they didnt care about race, eventually you would pretty much see everyone looking inbetween. After that i think they would have adapted to their enviroment a little bit, making them even a little more contrast to all the others.
