Answer:
The gravity force equals your weight while you are at rest on or near the Earth's surface. The acceleration of gravity on a particular celestial body, such as Venus or the Moon, is different than on Earth, because if you stood on a scale, it will show you that you weigh a larger weight than on Earth. When a person is standing still, the action of the Earth on their body is a gravitational force.
For a person standing on the ground the Earth pulls on the person with gravity, so the person pulls on the the Earth with gravity. 3rd law force pairs are always of the same type (in this case gravity) and always act on different objects. For your example one acts on the person, and the other acts on the Earth.
