Long ago a lot of people thought the moon was a God . Other people thought it was just a light in the sky . And others thought it was a big ball of cheese .
Then telecopes were made .And men saw that the moon was really another world . They wondered what it was like . They dreamed of going there .
On July 20 , 1969 , that dream came true . Two American men landed on the moon . Their names were Neil Armstrong and Edwin Aldrin .
The first thing the men was that the moon is covered with dust . The dust is so thick that the men left footprints where they walked . Those were the first marks a living thing had ever made on the moon . And they could stay there for years and years . There is no wind or rain to wipe them off .
The two men walked on the moon for hours . They picked up rocks to bring back to us for study . They dug up dirt to bring back . They set up machines to find out things people wanted to know . Then they climbed back into their moon landing craft .
Next day the landing craft roared as the two men took off from the moon . They joined Micheal Collins in the spaceship that waited for them above the moon . Then they were off on their long trip back to earth .
Behind them they left the plains and tall mountains of the moon . They left the machines they had set up . And they left footprints that may last forever .
