quick fact before we get started.

when you destroy things, you are separating the molecules within that object, you are only breaking the molecules free of there attraction force between one another, the denser a object the more closer the molecules, the more the stronger the attraction.

a planet is a giant rock binded together by attraction from gravity.

if you are only overpowering the gravity that binds the planet together then that does not truly make you planetary you are only overpowering the force to move that mass. same thing with a rock and it's molecules, you destroy a rock. you don't truly destroy what is one that's why atoms are not destroyed and you don't really create what is one that's why atoms can't be create. you only bond things to create. and seperate them to destroy
