The verse above is a summary statement of God’s judgment at Babel, at which time God confused the languages of the people there and dispersed them throughout the earth. These original nations--all descended from Noah and his three sons--are listed in what is called the "Table of Nations" in Genesis 10. As time went on, the people proliferated into still more nations and languages and migrated still farther from Babel until finally, as the verse says, they were scattered "upon the face of all the earth."
Christopher Columbus was a brave explorer and skilled navigator, as well as a diligent Bible student and convinced Christian. However, he did not "discover America," as he is said to have done on October 12 in 1492. Neither did Leif Ericsson or any other adventurer whose name has been suggested for this honor.
The Indians discovered America! Archaeologists have found Indian artifacts at occupation sites dating well before the time of Christ at many places in America. And wherever these early tribes went, they carried with them the pantheistic religion taught to their ancestors at Babel by Nimrod there in that first great city after the Flood.
Many centuries later, however, there was another great scattering with a much different purpose and motivation. "Therefore they that were scattered abroad went everywhere preaching the word" (Acts 8:4). This time, it was not a false religion that was being carried with them, but the saving gospel of Christ who had commanded His followers, "Go ye into all the world, and preach the gospel to every creature" (Mark 16:15), even "unto the uttermost part of the earth" (Acts 1:8).
