They could tell, because rotation is an acceleration and accelerations can be sensed.
Think if you're in a chair, close your eyes, and you get spun in a circle. You'd be able to tell you started spinning, right? Your arms would want to move up, if you spun fast enough you'd get light headed. Because spinning is acceleration, and accelerations can be sensed.

thank you for your answer. it is just not intuitive for me that you can distinguish between acceleration/rotation and no acceleration/rotation without any reference system:
you can't tell if you are moving in a translation without reference. in contrast you can tell that you are in a rotation. Is it just a 'property of space' i have to accept or is there any deeper reason.
