<reasoning>

Identify the physical interaction

The interaction between you and the Earth is governed by Gravitational Attraction. Every object with mass exerts a gravitational pull on every other object with mass.

Compare the masses involved

According to the Universal Law of Gravitation, the strength of this pull depends directly on the masses of the objects. The Earth has an incredibly large mass compared to your body.

Determine the direction of the force

Because the Earth's mass is so immense, its gravitational pull dominates. This force acts along the line connecting the centers of mass of the two objects, pulling you directly toward the center of the Earth, which is downward toward the ground.
</reasoning>

<answer>
Earth's gravity pulls you toward the ground because of the gravitational attraction between your mass and Earth's mass. Since Earth is extremely massive compared to you, its gravitational pull is incredibly strong and acts directly toward its center, drawing you downward toward the ground.
