Because they are so far away
A unit is what we measure something in. It helps us know both what is being measured, and the scale that is being measured. For example, if the unit is an inch, then we're measuring the length of something relatively small. If the unit is a lightyear, then we're measuring the distance of something huge (most likely the space between things in outer space).
