Yeah, Ivan, I get what you're saying. However, in the flat earth model the Southern Cross (and all the other stars in the southward direction) would have to move all the way around the earth, so it would move in a predominantly westward direction. But it doesn't, it moves in a small circle around the celestial south pole.

Also, if you were far enough south (inside antartica) you would probably be able to see the constellations at exactly the same time (from locations on opposite sides of antarctica) since you can have like a 20 or more hour night.
Okay Tom. I already said that I do not have "testimonials or first hand accounts." What I'm relying on is a LACK of testimonials and first hand accounts. Let me try to put this as simply as possible:
-The Flat Earth model that you present implies that stars in the southern sky behave very differently than the standard consensus on how they behave.
-There are a lot of people in the southern hemisphere who look at the sky.
-If they saw some large weirdness in star behavior (like if they saw different constellations like you say they would) they would say something & it would be a big deal.
-But they haven't.
-So your Flat Earth model is incorrect.
I mean, I don't have any first hand accounts of huge yeti running through the streets of New York yesterday. And I think that's pretty good evidence that no yeti ran through the streets of New York. Don't you?
& you could probably get testimonials. I don't really care all that much.
