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

actually
u have asked a good question
i have ur answer
its a small colective work of number of waves
this needs a wave thory explanation
in simple terms
if u program a ball to go right
now if u add a program that if the ball touchers another ball it will also go right
then all will go right till the end or till a relativly slower object is encountered
the energy gets bigger and bigger and so the going to the right becomes slower so energy of direction becomes its energy to run its program
