I'm using the parabola to show you what the angle difference looks like at different altitudes.
Except you aren't, as you still have no explanation of how any of it works.
Problem 1: As you can see, because of the square-cube law, it is large enough to completely swallow the Earth.
This is not a problem.
Again, the sun is far away, which makes it look small.
The fact you need to continually contradict yourself, switching between the sun being so large it would take up your entire FOV; and the sun being so small it shouldn't be visible, should highlight this blatant dishonesty.
Yet here you are, happy to keep up this lie.
So let's use vanishing point to try to shrink it instead.
Problem 2: We quickly understand that even drawing straight lines the reason they call it vanishing point is that the angles intersect, and you sorta kinda can't see things anymore. To simply apply distance indefinitely so that a big object will be smaller violates laws of perspective.
WRONG!
The entire point of the vanishing point is that it is where PARALLEL lines intersect.
They do not do this after any finite distance. It takes an infinite distance to do this.
There is no beyond the vanishing point as that would require more than infinite distance.
Again, it truly is quite simple, if you have an object a height of h above a straight line, passing through your eyes, and it is a distance of d away along that line, then the angle to it will be atan(h/d).
This angle gets smaller and smaller and smaller, never reaching 0, but approaching 0.
It would require an infinite distance for that to reach 0. And at that infinite distance, it doesn't matter what the height is, the angle will be 0.
That is the vanishing point.
There is nothing that violates perspective (reality perspective, not your dishonest, delusional BS) about having a far away object appear smaller, with more distance making it smaller.
So still no problem for the RE, just more pathetic dishonesty from you.
You see, by the time that I got an object 5x times bigger to be the same size, it was almost gone.
By arbitrarily drawing in lines, however you like.
But even using that, you can make it any arbitrarily small size (including one right near the vanishing point where you need to zoom in quite a lot to see).

See how it is really tiny as it approaches the vanishing point?
And if done honestly you also need to note that the distance in this image represents a greater distance the closer you are to the vanishing point (which is why the thing appears smaller).
I think it disappears before getting close. You know how I know this?
You don't.
You falsely believe it, as it pure BS.
And you believe this because you need it to prop up your fantasy and pretend there is a problem with the RE.
Because I've now watched a complete sunrise and sunset, and it seems the sun needs to only go a little off angle in order to disappear. Our eyes simply aren't able to see endlessly.
And how does it disappear?
Does it just vanish, high in the sky, still quite large?
Does it shrink to a point and vanish?
Or does it get blocked by Earth?
Every time I have seen it, it is getting blocked by Earth, showing the curvature is making it disappear.
That is NOTHING to do with your eyes (other than their position).
But never you worry, I have yet another problem with this. Let's remove all but the sun that shrunk to equal size.
You are yet to demonstrate any problem, so you can't possible have another.
Now, I'm gonna use the Supernova feature to get this to shine like a motherf***er. I'm gonna make it shine all colors for rainbow sparkle princess magic.
You mean you will apply a crappy effect, which has nothing to do with how light works in reality.
You wont use the actual brightness of the sun, as observed by someone directly adjacent to it, nor will you even attempt to model how that should vary with distance.
Instead you will just a crappy effect which tells you nothing, and then blatantly lie about. So yet again, NOT AN ACTUAL PROBLEM, just more dishonest BS from you.
If you want an alternative to your dishonest BS, how about this:

In this one it looks like the light from the sun reaches Earth just fine, and even goes past it.
Now why should we accept your garbage rather than this garbage?
Yet again, you just making up BS to pretend there is a problem.
And don't, worry, I can even do the same dishonesty for your later BS (I made 2):

Looks like your sun is too far away to illuminate Earth at all. It must be only a few m above Earth, and only illuminate an area a few km wide.

Looks like your sun is too close, and causes all of Earth to be illuminated.
If you want to try modelling this honestly and accurately, you need to work out how much light the sun would be producing.
If you want, you can get an idea of that, by heating an object to 6000 K (roughly the temperature of the surface of the sun).
This is likely going to be a significant limitation, as it is quite difficult to heat an object to 6000 K, without it vaporising.
Your best bet is a flame or other plasma, and even that will be hard, as most flames don't burn that hot.
Then you need to note that the energy given off is based upon area.
And the way it appears to diminish with distance is also based upon area.
This is because the light spreads out in a sphere.
This means you need to scale that brightness for the brightness of the sun, based upon the surface area of the sun, and the surface area of your hot object. And you need to scale it based upon your distance from the object (or otherwise obtain the total energy given off).
Long Sun Paradox.
Already demonstrated to be pure BS, which you just ignored because it shows you are wrong.
So no, you lose.
And are just further demonstrating your dishonesty and desperation.
The sun can only appear that size and provide that amount of light and warmth, if it is actually that size, and the space is different from what you proposed.
Or if it is the size the mainstream model has it as, the distance the mainstream model has it as, and the brightness the mainstream model has it as.
Again, you are yet to demonstrate any problem.
Instead you just whatever dishonest BS you can, to blatantly lie to everyone and pretend there is a problem.
You move out of angle range and the sun doesn't give off heat and light as much.
No, you move to a position where Earth blocks the view, and you can't see the sun.
Meanwhile, the overly convoluted idea that the sun is big but appears small due to distance simply doesn't pan out.
There is nothing convoluted about it.
You are not standing next to the sun, so it is clearly distant and appears smaller than it would if standing right next to it. The only question is how small, and how far away.
I hope you're happy. GIMP stalled on me, and an art project that should have taken 30 minutes took nearly 3 hours.
The art project should have taken no time at all, as you shouldn't have even attempted it, as it is dishonest BS.
If you had any sense of integrity you would have known that before you started it and decided not to.
