Have you ever seen the Earth move? Have you ever seen the Sun move?
If so, how?

I see the earth moving all the time. Take a look at the sun, it moves across the sky all day long, and then guess what- it becomes night! And then the sun rises again the next day. All due to the Earth moving.

Every day and every night. The sun sets and rises because of the rotation of the earth. Motion. The sun sets earlier and earlier and rises later and later these days because the earth is also moving along in its orbit around the sun. You can also observe the stars and the constellations which rise and set just like the sun. The movement of Mars also gives proof of the earths movement around the sun as Mars on occasion begins to move backwards...

The actual motion of the sun is more difficult to observe but it is possible. The sun has sunspots and by using special telescopes (don´t look at the sun through ordinary telescopes or even your eyes!) you can see that they are moving as the sun rotates. The suns movement around the galactic plane is even harder to observe. You need to take a picture of the sun so that the stars are visible at the exact same time once a year (SOHO can do it). If you do this for long enough you will be able to see that the sun and the stars will not be in the exact same position from year to year. The sun and all the stars will have moved ever so slightly in proportion to one another.

Well, I've experienced several earthquakes, but then I _felt_ the Earth move, rather than _saw_ it. However, I see the Earth move every time I look through a telescope without a motor drive. The telescope is fixed to the Earth, the Earth is rotating, and I see the magnified images of the stars move across the field of view at an obvious speed. At public and school star parties I often bring an undriven telescope exactly because it demonstrates to anyone looking through it that the Earth does in fact rotate.

When a Star is so far away , it motion is barely detectable ,Hence we consider stars as fixed.
However in the night shy you see the stars moving. This motion is called relative motion. The relative motion we observes is really the motion of the earth relative to a fixed star.
We cannot see the Sun motion of the orbit relative to the Earth-Sun system barry center,because the Sun's orbit is very small compared to that of the earth's motion relative to their common barry center.

Both the Sun and the Earth also move relative to the Milky way barry center.And the Milky way also is moving relative to the dynamic barry center of the Universe.
In any case the Barry center of the Universe is not an absolute fixed point ,since it is dynamic and continually moving trying to maitain gravitational equilibrium in the Universe.

Yeah, I experienced the Loma Prieta earthquake. I've seen the earth move. I've felt like I've been surfing the ground.

As far as the sun goes, no. The sun moves very slowly relative to other things. I've seen the effects of the earth's rotation in the sun rising and setting. I see that every day.

It is possible to see "something" move by noting that the sun appears to cross the sky. That could be either the earth or the sun moving in relation to the other, but one of them is on the move.

Accepted dogma is that it is the earth rotating on its axis.

Earthquake: the earth went up and then went down.

I see the Sun has moved, though too slowly to perceive by staring at it (which is bad for the eyes).

yes. you can observe the motion of the sun against the background of the galaxy over an extended amount of time.
