We argue, through some philosophical considerations, on (i)dependent or (ii) an independent existence of physical reality underlying quantum states. According these simple considerations, we conclude that is impossible to have a clear independent existence of physical reality, we need to search the reasons in the relationship between our questions (the observers) and the consequent answers (always estimated by the same observers). Finally, we infer that every theory is affected by our "questions", so we cannot speak about an unconditional and independent theory underlying physical reality. Plan of the paper. The existence of physical reality underlying quantum states: (i) it before bit,(ii)it without bit,(iii)it from bit.
