We have different time zones because if we all set our clocks to the same time noon would be the middle of the day in some places, but it would be morning, evening and the middle of the night in others. Since different parts of the Earth enter and exit daylight at different times, we need different time zones.
Time zones make it so that everyone has the same pattern of sunrise in the early morning and sunset at night. We need time zones because the earth is curved, like a ball. As the sun shines on the earth, not all places get the same amount of sunlight. The sun shines on one side of the earth and makes it light out (daytime), while the other side is dark (nighttime). If time zones didn't exist, many people around the world would have very weird patterns of sunlight during the day.
