One time long ago there were people living on an island who had never had contact with anybody else. They marveled at the nature around them and dreamed of harnessing it. They looked up at the moon at night and said "Some day we will go there."

But they lived in grass huts and the highest they had ever been off the ground was when they climbed a tree.

One day a genius was born on the island. She built a structure taller than the tallest tree. "I call it a stepladder," she said. The people were amazed. They climbed the stepladder and looked down upon the treetops.

The people proclaimed "All we have to do now is make this a little higher and we can reach the moon!"
