Why do you need to use a reference point to tell if an object is in motion?

Because there's no such thing as "real" motion. There's only motion compared to
something else.
You can't read a book if the book is moving. But you can read just fine while you're
traveling in an airliner. Compared to your lap and your eyes, the book is not moving.
Compared to the librarian that you're flying over, you and the book are both moving
at 400 miles an hour.
Well, which is it ? Is the book motionless or is it moving at 400 miles an hour ?
The answer is: Yes. It's both, depending on the reference point.

Is a reference point the object to which we compare another object's motion?
Yes, that is one meaning of "reference point", although the reference point need not be an object, but may simply be a location.
Why do you need to include a reference point when you describe the motion of an object?
Motion is relative. There must be something to compare it to.
What do you need to describe the position of object?
we need a fixed reference point to describe the position of a body
What information do you needs to describe an objects location?
To identify and objects location you need three pieces of information. These are a reference point, a distance from the reference point, and a direction from the reference point.
What type of object other than unmoving objects can be used as reference points?
Any object can be used as the reference. There's no such thing as an 'unmoving' object. It's only unmoving relative to itself or to other things that are moving exactly the same as the object. That's the whole reason that you need a reference point.

Why do you need a reference point to know an object is moving?
A reference point is part of the definition of movement or displacement. The difference, over time, of your distance or orientation to a given reference point or points defines movement.

What information do you needs to describe an objects location?
To identify and objects location you need three pieces of information. These are a reference point, a distance from the reference point, and a direction from the reference point.
What else do you need to know to find an object besides the reference point and distance?
One needs the direction.

Is a rose bush and object in motion?
no not really but it for shure does need a motion to this you know like a motion.
What is A object that stays in place and to which a moving object is compared is a?
A reference frame? Of course, a reference frame need not be a specific object, so I'm not really sure...
What do you need to find the speed of an object in motion?
radar gun
