Believing something to be possible or impossible is wholly different then something actually being itself existing as possible or impossible for others.
For me, possible and impossible require conditionals to define the parameters respectively. Without conditions to preclude one over the other, neither can exist as truth. In fact, without conditions, both possible and impossible can only exist together in falseness.
Those requisite conditions can only be discovered and realised from a relative point of observance to either true existing state. Therefore, whatever is possible or impossible respectively is defined by the limits of one's capacity to experience relative observance of whatever.
