In the biblical story of the Tower of Babel, humans initially all spoke one language. They wanted to make a name for themselves and began construction of a huge tower to reach the heavens. As the tower grew, God saw the hubris of the humans and came down to confuse their language ("babel" comes from the Hebrew word "to confuse"). The architects and workers, now all speaking different languages, were no longer able to communicate and abandoned construction. They then scattered across the world...and the human translation business has been booming ever since.
