Terminators.. HMMMM

Did you ever wonder who was John Connor's original dad, before the time paradox where Kyle Reese impregnated Sarah with awesomeness?

Or is it that he never had another father, Reese was always his true father and the resistance exists just because Kyle Reese traveled back in time to create the leader who sent him back in time, creating an infinite loop?

Is it possible that John never existed in the first place & Kyle made this shit up just to shove his dick in Sarah and as a side-effect he created the resistance and everything we see in the first film is a part of the infinite loop that Kyle created just because he wanted some radioactive-free vagina?
