The appearance of motion is there certainly, and in the reference frame of Earth's surface it can be said that the sun makes a circuit around the Earth, though it isn't technically accurate in terms of actual motion it is a valid perspective. Tycho Brahe's model though?
Actual motion? All motion is relative!
There is not ether, not absolute motion, so we simply choose an inertial reference frame and as long as we stick with it, we'll be fine.
Hey, the Tychonistic system is cool. Geocentrism and heliocentrism, all at the same time!

No, it has to do with wether you paid attention or not in highschool.

Why? Have you gone through the relevant calculations and made the measurements so that you can say with confidence that you know geocentrism is wrong? For all that you can actually say or prove, there is no reason to favor either heliocentrism or geocentrism.
Its been a few years, but the answer is YES!
If you were to observe the position of the 5 planets visible to the naked eye in the night sky over a period of say, 6 months, they have a tendency to appear as if they are moving across the sky and then turning around and moving in the opposite direction! 
You DO realize that the interplanetary probes that we have launched are guided using Heliocentric and NOT geocentric coordinates. If geocentricity were correct then a probe launched from the Earth would fly out into space in a arc away from the Earth, and since this has been MANY times(like the 15 missions to Mars by the NASA) and the probes DO NOT follow such a path! They follow a spiral pathway which is what the heliocentric model predicts as they are under the influence of the suns gravity.

We are not in an inertial reference frame.

Wrong. There is no physical basis for geocentrism. The model wherein the bodies of the solar system revolve around its center of mass is consistent with the laws of mechanics and gravitation.
