I failed all my science courses, I don’t understand much about science but why doesn’t the water just… move like when you jump in normally?

It does, but your body has to push it aside – it doesn’t just part for you. Water has weight and inertia like all other matter, and currently it’s “somewhat heavy” and “hardly moving at all”.
Think about atmospheric re-entry of the space shuttle… why doesn’t air just move out of the way of the incoming spaceship? It wants to.. it can, but the ship is moving *fast* and there’s still some resistance there. The result is the space shuttle heating up from compressing the air.
While you’re not moving as fast as the space shuttle nor nearly as large, water helps make up for it by being much denser. The problem remains: your body has to move water out of the way fast enough for your body to go into it. The faster and the larger area you hit, the harder the water resists and hence the more painful the impact. The fact that water doesn’t compress doesn’t help matters either.
