I'l ask you a question, by saying zero is nothing you made an absulute assertion, by you saying zero cannot be something you yourself are setting an apsolute impossibility. Is impossible for zero to be something or is it possible for zero to be nothing? it is mutually binding and amounts to impossibility. So it is not possible that zero does not exist, it exist very much, for you made a possibility for SOMETHING (in this case zero), to be nothing. Zero is that SOMETHING thefore exist. Doktor Doktor you are right, there absolute are absolute impossiblities, it is not possible to experience daja vu for the first time.
