"Why [does] a person fall toward the earth when he falls from height? An apple is so near to the surface where the g (accelration due to gravity) is highest but it also fall after a very lagre time but when a person falls from a height their the g is also less and his inertia is also more as compared to a apple." (sic)
It's because the Earth's mass is about 5973.6 yottagrammes. I think you're making the mistake of equating a sphere with a point particle, resulting in misguided and irrelevant comparisons.
