'Stationary' can be understood as 'not moving' and that as 'having 
velocity zero'.

But velocity would require a reference point, in respect to which the 
object does not move.

But what was actually Einstein's reference, in respect to which velocity 
v was measured.

Usually we could take 'the universe' as kind of background and Newton's 
absolute space as reference.

But this wasn't possible, because Einstein had explicitly excluded 
Newton's absolute space.

But if not that space, then what else could you take?

I suggested the following concept:

the observer always takes the own position and assumes, that would not move.

This assumption is wrong, of course.

But what else could you take???
