Its not strong enough
The motion of the sun will stop because the sun will crush on the earth if the gravitational field of the sun collapses.
it doesnt the moon is drifting away from earth's gravitational pull by 1 half an inch every year
Mainly because we are in "free fall" around the Sun. In such situations, gravity won't be noticed. Also, Earth's gravitational force is much stronger, anyway, because Earth is much closer.

Because Earth's gravitational pull is far greater than any gravitational pull possessed by humans..
Look at the formula for gravitational force. It depends on BOTH masses - as well as the distance. In this case, Earth has a large mass, people have a small mass.Also, people just "move along" with Earth - if the Sun pulls on Earth and on us, we accelerate TOGETHER towards the Sun.
The gravitational pull of Earth keeps objects and people on the surface rather than floating off into space. The gravitational pull of Earth causes the tides in the oceans by attracting water towards the center of the planet.
Because the gravitational pull of the Earth is much larger than the gravitational pull of lets say... a human. You could argue that on earth there is a gravitational pull to humans, but the Earth is over powering that pull. So the object is pulled down (to the surface of the Earth) rather than to you or me.
yes but only 1/6th of what we feel on earth
No, not only the earth and all of the other known planets have a gravitational attraction, but any object of any mass carries with it a measurable gravitational attraction to any other object of mass. Which is why it is said that the moon doesnt just revolve around the earth, for instance, but that the earth and moon REVOLVE AROUND EACH OTHER.
Mars orbits the sun instead of Earth because all planets, including Mars, orbit the sun due to the sun's gravitational pull. The gravitational force exerted by the sun on Mars is stronger than the gravitational force between Earth and Mars. This gravitational force keeps Mars in orbit around the sun.
The Earth's gravitational force acts towards the center of the Earth.
