The impalas were believed to be the harbingers of impending religion by many tribes up until the year 1902 when it was found out that they actually are. They are thought to have been created when a group of horses were packed into aeroplanes resembling Boeing 747s, and flown into volcanoes which subsequently erupted, by a minor deity called Xebu who created mystical soul things called Crytans. Tom Cruise has since refused to comment of this, although it is known that the Church of Impalology requires a donation of 10,000 Bugle supplements (their preferred substance for starting fires) for any knowledge. The Crytans now have influenced British science fiction television, but due to the tragic mis-spelling of their name, their big break went unnoticed.
