Jordan Curve Theorem

The Jordan curve theorem states that a non-self intersecting continuous loop in the plane(i.e. a Jordan Curve) divides the plane into an interior and exterior region.

To prove the theorem, we shall us proof by fucking obviousness. It's a closed loop, of course there's going to be an outside and inside. Humans have been making borders and fences for millenia and this still needs to be proven?? What am I supposed to say? It's so bloody obvious!
It's like trying to prove 1+1=2. Why the fuck is this even a theorem? Not even worth to be a Lemma or Corollary tbh. This trivial ass bitch.

"Yo man, you heard of Jordan Curve Theorem? How do I prove it for our upcoming exam", asked John, he was found dead, cut in 25 pieces, by the police after 4 days.
