Absolutely. I'm inclined to doubt it. Too little information. Its possible, but, that's all I know.
I think language and religion itself are powerful indicators, then there are the common thread in mythology. People in northern Burma have stories of old that we all at one time lived in one large village and spoke the same tongue, we started to build a tower to the moon but since it required working on separate levels they lost touch with one another and gradually acquired different customs, and speech.
In northern Siberia the Yenisei-Ostyaks have the legend of the people who had saved themselves from a flood by floating on rafters until a strong north wind scattered them so that they began to speak different languages and form different peoples. The early Aztecs thought that after the Flood a giant built a hill that reached to the clouds. This angered the gods who then cast fire or a stone down upon them from heaven. The Maya have Votan, the first human helping to build a huge house that reached into the heavens. It turned out to be "the place where God gave every tribe its particular language." The Maidu Indians from California claim that at a funeral ceremony everyone suddenly started speaking in different languages.
I wouldn't say that it was a belief of mine, I would say that it certainly seems plausible and could possibly explain a great deal.
