gravity is the force of attraction of the earth to a body causing the body to accelerate at 9.81 meter/sec^2
g = 9.81 m /s/s is sometimes called also as the gravity
force is not the acceleration . . . in second law of Newton
. . . . . F = ma
for every acceleration there is always a net force causing it
also . . force every force acting to a body will cause the body to accelerate depending on the mass of a body.
again . . gravity is not the acceleration but a force of attraction
there is another force named as the universal force of attraction
. . . . . . F = k (M m) d^2
the force of attraction between two bodies M and m is directly proportional to the product of the masses of the two bodies and inversely to square to the distance between them

Gravity is a theoretical (yes it is only a theory as of yet) force that holds all objects towards the center of whatever object it is coming from.

Classical physics:
Gravity is a force that pulls objects together. The force is proportional to the masses of the objects and inversely proportional to the square of the distance between them.
Modern physics:
Gravity is the curvature of space and time due to the presence of matter. The amount of curvature depends the mass.

Gravity, as we call it is the attraction of one heavy object (earth) to another object (everthing else) it is pretty common in physics, like when you say opposite charges attract.
It actually has nothing to do with the earth in particular as it can be proved that any object is capable of attacting another object (even us!)
I'm not exactly sure about this since its been two years since i took physics, but i'm reasonably sure.

It is one of the four forces of attraction in the universe.
Although there are apparently many types of forces in the Universe, they are all based on four fundamental forces. The strong and weak forces only act at very short distances and are responsible for holding certain nucleons and compound nuclei together. The electromagnetic force acts between electric charges and the gravitational force acts between masses.
