the southern part of the Rhinns came into being 1,800 million years ago, a period of time which altogether defeats the imagination. The English Channel, for example, did not exist 8,000 years ago; England was then part of France and the European mainland. The stone of the Rhinns coming into being is 225,000 times more ancient an event. Another way to put it is to imagine the earth's history as a 24 hour day. Human beings have evolved in the last 8 seconds of that day alone; even the dinosaurs didn't appear until 22:48(and they lasted just 51 minutes). These rocks, by contrast, date back to shortly after lunch.
