I think they both revolve around their common center of mass. Of course, since the sun's mass is so much greater than the Earth's their common center of mass is inside the sun, and it appears almost as if the Earth revolves around a stationary sun.
they all have something to do with light but the earth shares the light with the sun as does the moon but on earth we have adapted from just using the sun and use man made light sources.ok?

They are important to earth
The combination of the Earth and Moon orbits the sun. That is, their common center of mass orbits the sun. Their common center of mass is the place where the pivot would have to be if the Earth and the Moon were on opposite ends of a see-saw. At the same time, both the Earth and the Moon are orbiting their common center of mass ... which is actually located inside the Earth, because the Earth has about 80 times as much mass as the moon has. Viewed by an observer on the sun, the Earth is in an elliptical orbit around the sun with tiny, almost imperceptible wiggles in it, and the Moon is also in an elliptical orbit around the sun, with much larger wiggles in it. The wiggles in both orbits repeat with a period of 27.32 Earth-days.
You're half-way there. The mutual, equal gravitational forces between the Earth and Sun maintain the Earth's stable, closed, elliptical orbit around the Earth/Sun common center of mass.
When the earth is between the moon and the sun, a full moon occurs. In the less common instance when the Earth is between the moon and the sun and all three are in line, a lunar eclipse occurs.
The sun and the Earth both orbit their common center of mass, as any two orbiting bodies do. Since the sun's mass is about 333,000 times the Earth's mass, their common center of mass is about 333,000 times farther from the Earth than it is from the sun. (Just the same way as the Earth and sun would have to be situated if the two of them tried to ride a see-saw together.) If the Earth averages about 93 million miles from the sun, that places their common center of mass something like 280 miles from the center of the sun ... about 0.03% of the distance from the sun's center to its 'surface'. That's why it sure looks as if the sun is just sitting there in the center and the Earth is circling around it ... because the Earth makes this enormous circle around the common center of mass, while the sun just barely wiggles.
You're half-way there. The mutual, equal gravitational forces between the Earth and Sun maintain the Earth's stable, closed, elliptical orbit around the Earth/Sun common center of mass.
Basically, yes, it is impossible for that to happen. Technically, both of them orbit their common center of mass as opposed to one orbiting the other. However, since the Sun is so much more massive than the Earth, the common center of mass is inside the Sun, so saying that the Earth orbits the Sun is more or less true, and certainly a lot more true than saying the Sun orbits the Earth.
