"Energy is neither created nor destroyed but can be changed from one form to another."An object at rest in space now our earth goes near to it.we know it will be attracted by earth i.e it gets kinetic energy from where does it get this energy?

The Earth's gravitational field.
Explanation:
Without getting too complicated:
The object is in the Earth's gravitational field. This gravitational field gives the object gravitational potential energy. This potential energy can be converted into kinetic energy.
Using the example provided, the Earth is moving closer to the object. This means that the distance between the Earth and the object is decreasing. As a consequence, the gravitational potential energy of the object will decrease. Any energy lost as gravitational potential energy is gained as kinetic energy.
