Motion and rest are relative terms.

A body is said to be in motion when its position changes with time with respect to the observer. Eg. A person in space will find earth in motion.

A body is said to be at rest when its position does not change with time, again with respect to the observer. Eg. A person on ground will find tree at rest.
