I mean how do we know since we do not have a fix point in our solar system.

There are no 'fixed points' in space. We can only talk about how things move relative to each other. This does not mean that there is no difference however between the sun circling the earth and the earth circling the sun.

the problem with believing that the sun circles the earth is that you would then have to come up with a reason for why the other planets move as they do. Their apparent positions in the sky during the year are not consistent with things that orbit the earth, they only make sense if they are orbiting the sun, and if the earth is orbiting as well.

Also you would have to disregard what space agencies such as NASA, JPL, ESA, and the Russians have told us, and all of the evidence collected by space probes launched by the various countries. Their trajectories are carefully planned to intercept other planets based on the idea those planets are orbiting the sun along with earth.
I suppose you could say 'it is all a conspiracy', but I do not think we as a society are good enough to keep something of that magnitude a secret...

If we were just looking at Earth and Sun in isolation you'd have a point. However, whilst we do not have a fixed point, but we do have extensive observations of other bodies in the solar system, and other scientific ideas that fit the idea of Earth orbiting the Sun.

Planets and other bodies show retrograde motion, which either requires a separate solution for their motion for each body, or else requires that we are moving. It just so happens that the single step of making the Earth orbit the Sun explains all the retrograde motions of every other body in the solar system. We also observe stellar parallax, which is consistent with Earth being in a 150 million km radius orbit. Additionally, direct observation of other objects shows that smaller bodies orbit larger ones, and that the Sun is considerably larger than Earth.

If Earth is static and central then all these observations require separate explanations, but if we make Earth an orbiting body everything is explained in one fell swoop. Occam's razor applies.

Forgive me if i did no longer comprehend element of your question, yet whilst as i think English isn't your community language, you communicate mine plenty greater useful than I communicate yours! That video is, as you have faith, total rubbish. no longer slightly fact in it. evaluate that we comprehend planetary action o.k., based often on the guidelines of Newton and Kepler first widespread 1000's of years in the past. As evidence, evaluate the Voyager 2 spacecraft, which became into despatched purely approximately 3 billion miles to Neptune, and arrived interior of a few thousand miles of its objective factor. If this moron's video had ANY fact in any respect to it, we would by no skill have come close! All planetary orbits are elliptical, a fact that has been conventional and regular for centuries. bear in techniques which you additionally can locate human beings on youtube and someplace else on the internet who declare that the earth is flat, the earth is hollow and extraterrestrial beings stay on the interior, planet X exists and is approximately to wipe out maximum life on the earth, and needless to say all the 2012 doomsday fairy memories. You sound such as you're clever, save thinking all people making claims that look opposite to good judgment. bear in techniques the words of the great astronomer Carl Sagan: dazzling claims require dazzling evidence.

Yes, I do still believes that the Sun is circle the Earth, because that's what I learned from my teacher. I hope I helped.
