the moon is not falling because the gravitational force of earth is balancing it.

nice question ,
according to Isaac Newton , the force that makes apple fall on the ground also keeps moon in the orbit of earth . it isn't falling because it has its own gravity but due to less mass its gravitational pull is not strong enough to pull earth towards it , moreover , it is said that every year moon comes closer to earth about a small distance (not small, very very small)
according to Albert Einstein , space and time are not 2 separate entities but rather a very same entity . mass or energy curves fabric of spacetime and the body having lower mass fall towards the body which has higher mass . the linear motion in space is straight so when a heavy body curves space-time the lighter body falls towards it
so , ultimately there's no such thing as gravity according to Einstein and indeed , moon is falling towards earth
hope this helps
