Genesis 11 describes the Tower of Babel account when God confused the language people spoke at the time. From then on, there were 70 language groups.
What is interesting is that the language families we currently have correspond roughly to those mentioned in the table of nations in Genesis, providing proof of the accuracy of the Bible, as this brief video produced by the Institute of Creation Research (ICR) shows.
