Because the Earth is being pulled towards the sun like we are. But we are also moving in a perpendicular direction of the sun's gravity which is the basis of orbit.

the earth is moving an orbit that is it is falling freely toward the sun but going around at the same time the sun pull us in the same orbit so we move with the earth
the earth pulls us to the center of earth but the ground keeps us from falling so we feel the weight of our body mass on our feet ( or backside if we are sitting in a chair)
Newton was pretty smart to figure this out . it is NOT obvious

Well, ..., because at some point the Sun's gravitation pull is negated by Earth's gravity (Those points are known as Lagrangian points and there are 5 of them). After which the Earth's gravity becomes steadily stronger keeping us pinned here. See below.
-
Because of our closeness to the Earth, it exerts a greater gravitational force on us than the sun.

Idiot!
-
Because the Earth has a stronger pull on us than the Sun does. Simple enough.
