Really? That does not answer why the Sun circles and the asteroids fall down.
How do you know that asteroids cannot come from the direction of the sun?
No one said anything about the direction of the Sun, just the physical location.
There's not nearly enough of a question there for more of an answer to be merited. It's the obvious response; why would the Sun fall down if asteroids do? Why wouldn't asteroids fall if the Sun doesn't? They're different objects, in different locations, with differnet velocities. Beyond the easier models, you don't even need to get specific with the physics, whatever force makes everything else stay up in repeating motions, the chances of it being stable everywhere for all things are kinda absurdly small.
So what holds the sun to its highly complicated path over the flat earth - spiralling from the Tropic of Capricorn north to the Tropic of Cancer and back each year?
And it's not just the sun. Are there these
special unmarked stable highways in the sky for each of the innumerable celestial objects?
Genesis 15:5
‘Look now toward heaven, and tell the stars, if thou be able to number them': and He said unto him, 'So shall thy seed be’.
There are estimated to be 6000 visible stars, 10 times that visible with a modest telescope and an estimated 250 billion in the Milky Way.
And all within you "dome"? So there seems little "space" among these stable "physical locations" for these unstable asteroids.
You are correct in the sense that all of the objects could be said to be in orbits and asteroids just happen to hit the earth when these orbits intersect.
But it's a bit hard to explain the annual meteor showers on the flat earth.
With the heliocentric system it's not an issue. The earth's orbit just intersects the highly elliptical orbit of these bits of comets
On the flat earth, however, there does not seem to a plausible mechanism to hold any of these objects up there.
There are lots of guesses and hand-waving but little else.
And yes, I read the rest of your post and chose to ignore it.
