Please explain the earth moon sun system cannot describe the cyclic patters and eclipses of the sun and moon

I only need an explanation for the picture.

Picture: The earth is in the middle with a long arrow pointing to the left at the sun, and a short arrow pointing to the right at the moon.

It means there are different timezones.

Explanation:

Example:

Chris discovered that his best friend, Mike would live on the other side of the world. (Chris is in USA, Mike is in Australia). So when Chris is rising up in the morning, Mike is already going to bed and vise versa.

81 is a composite number.
