Sorry. The title was shorten. And should read, “Perspective and vanishing point did not physically block duck from view.”
So. I placed this blue duck 58 paces from my SLR camera. The camera was placed with its base / bottom flat on the shop concrete. (I can get the exact distance, but why waste extra effort on flat earther’s!)

The duck is never physically blocked from view like this ship beyond the horizon.
If the earth was flat, the earth would never physically block the sun from view.
Perspective and vanishing point does not physically block objects from view.
The sun setting beyond the horizon to be physically blocked from view is a property and proof of a spherical earth. Especially in the case the sun is a single light source.
Look at you floor. Whatever length it is, keep it in mind.
Now, look at your second image, taken from near the floor.
How much of your image shows the floor? Over half of it, right?
The floor is flat, correct?
So this represents a flat surface, not a 'curved' surface.
How long is your floor? Let's say it is 20 feet long, for argument's sake.
Why does a 20 foot long FLAT floor, take up more than half your image? Hmm...let's continue..
What would we see if your FLAT floor was 40, or 80 feet long?
Would it keep rising, until that was all we could see? Or would it stop rising, and form into a horizon? It's easy to find out, with a longer FLAT floor, right?
If you have access to a FLAT floor at least 40 feet long, and placed your camera on the ground, same as you do here, what would we see? Would the horizon keep appearing to rise, and take up the whole picture, or only part of it? Let's assume we need a longer FLAT floor, to find out (which we WOULD need, btw).
Tell me why, when we are debating whether horizons form on flat surfaces, or not, you show us a floor which KEEPS rising, but it is not LONG enough to see if it KEEPS rising, and STOPS rising, and forms a horizon? The surface of Earth doesn't stop 20 feet out, so why would you show a floor only 30 feet long to represent it?
You know why, that's the reason your bunch only shows a SMALL length of flat floor, because you KNOW what happens over a LONG flat floor!
I've seen this little BS argument before. Someone showed me their small floor, admitted it WAS flat, and put an object at the far end, which was fully visible, and claimed 'objects above flat surfaces would AWAYS be visible'!
Anyone who uses their brain here, can see the flat floor STILL appears to be rising, hen it reached the end of your floor, right? You know that, don't you?
Are you trying to prove that horizons do NOT form on flat surfaces? Or that objects ABOVE flat surfaces would be seen, in their entirety? Maybe BOTH of them?
I assume you can see the flat floor STILL appears to be rising at the end of your floor, right?
Do you think the floor STOPS appearing to rise, at the end of it? No, I'm sure you know better than that.
Knowing the flat floor is NOT long enough, why do you SHOW that flat floor, as your example? I mean, you already KNOW it is not long enough, that if your flat floor was longer, the surface would CONTINUE to appear to rise, right?
Isn't that completely dishonest of you? If you know the floor is flat, and appears to be rising, you also know it STILL appears to be rising, when the floor ends, right?
So what are you REALLY trying to do here? Do you think this wouldn't be caught?
It's time to face reality, or go back and hide under your bed, buddy. I don't care what you choose, it's your problem
