The ancient Greeks developed a mathematical model of the universe as they understood it—Earth was at the center of everything and unmoving (after all, we'd feel it if it did move). Tycho Brahe developed a theory based on his observations that while Earth was still at the center of the universe, the planets all revolved around the Sun which revolved around the Earth. Interesting, this is geometrically equivalent to the actual motion of the Earth and all the planets around the Sun. He just got the dynamics wrong.
However, we now have evidence (parallax observations, doppler shifts, etc.) of the true motions in space. And, yes, the Earth did move for me.

That is the old theory. It is thousands of years old. The idea that Earth and all the other planets revolve around the Sun is the new theory. It is only about 400 years old.

Movement is a matter of having a point of reference. If your point of reference is the sun, the earth is moving around it. From the point of view of the earth, many stars are so far away that they do not seem to move at all, even though they are moving just as fast as earth.

OK, now figure out what force is causing the entire universe to move around the earth that fast.
