why does field's like magnetic field, gravitational field do not obey the first law of thermodynamics???i.e(energy can nither be created nor be destroyed)

I would like to know where gravity gets its energy to attract physical bodies?
I know that the law of conservation states that total energy of an isolated system cannot change. So gravity has to be getting its energy from somewhere, or else things like hydropower plants wouldn't be able to turn the power of the falling water into a spinning rotor.
Just to be clear, Lets create an example:
Lets say we have two objects with equal mass close to each other. So gravity does its job and it pulls each other closer, this gets turned into kinetic energy. This is where I'm lost. According to the law of conservation energy can't be created or destroyed and the kinetic energy comes from the gravitational pull so where does the gravitational pull gets its energy.
If that energy isn't being recycled from some where else then that means you have just created energy, therefore breaking the law of conservation
