People saw1 the sun rise2 higher in the sky during3 the summer than in winter. They counted the days that passed from the sun's highest position5 until6 it returned7 to that position. They counted three-hundred sixty-five days. We now know that is the time Earth8 takes to move once around the sun. We call this period9 of time a year. Early humans10 also noted11 changes in the moon. As4 it moved across12 the night sky, they must have wondered13. Why did14 it look different every night? Why did it disappear15? Where did it go? Even16 before they learned17 the answers to these questions, they developed18 a way to use the changing faces of the moon to tell time. The moon was19 "full" when its face was bright and round. The early humans counted the number of times the sun appeared20 between full moons. They learned that this number always remained21 the same -- about twenty-nine suns. Twenty-nine suns equaled one moon. We now know this period of time as one month.
