When was the Tower of Babel?

“To Eber were born two sons: the name of the one was Peleg, for in his days the Earth was divided, and his brother’s name was Joktan.” (Gen 10:25).  During the days of Peleg, all of the people on the Earth began their dispersal across the world.  It was at this time that the civilizations of Babylon (2234 B.C.), Egypt (2188 B.C.), and Greece (2089 B.C.) were born.  The days of Peleg and the dispersion of the Earth’s population have been calculated to happen 100 years after the flood, 2242 B.C.  The following link shows a chart of Noah’s family and which people groups and nations they formed: http://www.answersingenesis.org/contents/379/Table%20of%20Nations.pdf
