* Earth's Gravity is Constant: The Earth's gravitational pull is the same on all objects at the same distance from its center. This means whether you're talking about a tiny pebble or a massive building, Earth's gravity acts on them equally.

* Your Body's Gravity: Your body does have a gravitational pull, but it's extremely weak compared to Earth's. This is because gravity is related to mass, and Earth is significantly more massive than you.

Therefore, Earth exerts a greater gravitational pull on any object sitting on the ground than your whole body exerts on those objects.

It's easy to think about the size of the object, but the key is that Earth's gravity acts on everything equally, regardless of its size.
