Not me. Though someone made a convincing case to believe in the OT firmament. Simply because things spatially didn't add up.
No, it is not "round earth or not". I never said nor implied that. The fact is that the Earth is round. If it was a case of "not" you might be right.
In order for something to be a fact, it actually has to be
proven. The alternative is a fact by fiat, meaning "because I said so."
But we have pictures from space!
You mean like this?
Looks about as realistic.
Pretty pictures. Honestly, we don't know, unless we personally venture outside.
Personally, Flat Earth doesn't work for me, because the horizon would extend alot farther.
So were are running under the assumption for the time being that, yes, the Earth is round. And by firmament, it would be what most people call our ozone layer. The shape works because the way we see is more or less obstructed, due to curve (although I'm pretty tentative about the shape, Earth could theoretically look like a burrito, and we'd not know from maps).
But that's not the point. The point is what's
outside this layer. You see, somehow despite being at a high vantage point where you should be able to see around the curve you can see maximum 11-30 miles (nobody seems to agree).

But you can see light years away at night. At the same time, on a perfectly clear day (no clouds), you still cannot see stars. This suggests that our atmosphere is a sort of screen. But given the massive disparity of distance, how can we possibly know whether these stars are not just like a painted ceiling to look like stars in a night and clouds in the day. There btw is such a thing as glow in the dark paint. I could paint my room to have a cloudy sky look during the day and "stars" at night. And if you made a geodesic dome like that, well, you'd have basically a hemisphere.
Ultimately, no I'm not a Flat Earth type. I'm a Truman Show holographic universe type.
