A little story . . .
Once upon a time there lived these two dimensional people. They were happy being two dimensional, partly because they knew nothing else than two dimensions - width & length.
They could walk left, right, up & down. All was good in Two Dimensional land.
But then, someone from Three Dimensional Land reached down and lifted up one of the peeps from Two Dimensional Land, because in three dimensions there is also height.
To the peeps in Two Dimensional Land he just vanished, like magic!
This they could not explain no matter how hard they tried, it had to be the work of something 'greater' than they, of course? So, for centuries they created stories upon stories to explain this 'divine' intervention and though they were not entirely positive about their stories, after awhile they came to accept them as truth, after all, what else could it had been?
