Its not just the earth and the sun; its the whole universe.
Changing the center does not change any of the dynamics. (I know, its just a bit too much for your little mind)
Gravity shows that less massive objects are held in the sway of more massive objects and orbit them. Our Sun circles the galactic core, our planet circles the Sun along with the other planets, and small moons circle most of the planets.
Only in Bizzarro world do tiny objects hold massive objects in their orbits.
But it is fun seeing the intellectual caliber of those who deny Biology also has them rejecting Gravity, Astronomy, and Math.
Still no Bible quote to support your contention. Just your boundless ego that YOU must be at the center of the Universe. The Earth need not be at the center for God to see us or to love us.
