2.  The Sun appears  The sun makes shadow of sundial stick

3.  The difference between the dark nights and the daylight was probably the first division of time recognized by early peoples. They would also have noticed that the sun came up over the eastern horizon and went down again below the western horizon bringing darkness to their world.  During the day they saw that the shadow cast by a tree, a rock, or even their own body was long early in the morning and grew shorter and shorter until it disappeared when the sun was overhead in the middle of the day. They also would have noticed that the shadow grew longer again, on the other side of the tree, as night came.After awhile they were able to tell how much of the day was over by looking at the shadows. The first timepiece was probably invented by a person who put a stick in the ground and made marks in the dirt to show where the stick's shadow was every hour.The shadow stick is the earliest form of sundial. People judged the time of day by the length and position of the stick's shadow.
