The Sun revolves around Earth: It’s getting worst

This is taken from a post on a certain forum (I want to preserve anonymity):

The Sun has no atmosphere such as Earth, science says the Moon orbits because of the balance between inertia and gravity, constantly falling but never falling, understanding this, the Earth would crash into the Sun because the Sun has no atmosphere, the massive gravitaional pull of the Sun would have already crashed the Earth in it.

The Sun and the Moon are the same size, this why an eclipes looks perfect! If they were different sizes one would attract the other due to gravitational pull and collide, but if they are equal, they counter each others pull.

If the Earth did spin, WE would all be dizzy by now?

According to you’re science the sun and stars are the same, therefore they don’t move, Earth moves around the sun, hence, where ever the planet is around the sun, we should not be able to constantly see the constellations, there would be a point were the Earth would be on the other half of the sun and Earth would only be able to see the constellations coming around the bend. But that’s not the case is it!

If only for that single post, school is important. Oh, and the Earth is flat by the way! Why does everything has to be a damn conspiracy? The Earth revolves around the Sun, end of the story. Then what, other planets from our “solar” system also revolves around Earth I guess? Oh, and if the gravitational pull of Sun is too big meaning we would crash into it, do you really think the gravitational pull of Earth would be strong enough to keep the Sun revolving around us? That would mean comparing the Sun with the Moon in a certain way…In fact, that’s what the guy says: the Sun and the Moon are the same size!

Anyway, I don’t even know why I’m arguing.
