She often came this way. She stopped and sat on the fence, looking at the single, timeless standing stone. It always caused her carefully controlled mind to wander. Back and forward. Backwards, she wondered where they came from. What they meant? Were other stones buried by the sands of time somewhere deep around this one, perhaps in a circle? Maybe this was a lone stone. Perhaps meant to cure sick children? How will we ever know, she wondered, what the prehistoric people who raised these stones really were doing.

Then there was that other theory. The one that some thought explained the pyramids as well as the standing stones. The theory that said that we weren’t alone in the universe. Perhaps other beings had helped those prehistoric people build these complex stone structures. Most discounted that theory of course, but she found herself thinking of it. It seemed so impossible that the prehistoric citizens could have done it themselves.

A timeless mystery of the universe. She started walking again, her imagination making her smile.
