Those are pretty pictures. However, they all have one thing in common. You can draw a straight line across the horizon.
That is possible when the Earth is flat.
Pure BS.
Firstly, the horizon is not a straight line in those photos.
The hills and trees make it not straight.
But more importantly, there is still no explanation for the horizon in a FE, so no, that is NOT possible if Earth is flat.
If Earth is flat there should be no horizon.
But with a round Earth, the horizon will be the same angle of dip all around, and when close enough to sea level (or ground level if the ground is level around you), that will appear in photos quite similar to a straight line.
As for your assertion that light can't bounce off and create light reflections, of course it can. It does so all the time!
Casting reflections isn't the issue, being bright enough to cast light and shadows upwards, while the sun is meant to be above casting light downwards is.
Light from a distant sun hits the clouds and brightens them, and the clouds are lit upward.
How?
The sun is above the clouds. How is it lighting them up from below?
Btw, this is impossible from a round Earth with a distant sun. The sun is too high, and could not possibly appear below the clouds.
Wrong again.
It is impossible on a FE with a sun that circles above the FE.
In that delusional garbage, the sun remains well above the clouds, and can't appear below the clouds, or cast light upwards on them.
But for a RE, the angle to the sun changes quite a lot.
e.g. On the equator, at midnight on the equinox, the sun is below you, literally above the opposite side of Earth.
So it most certainly can appear below clouds.
I'm pretty sure you have had this explained to you before.
But that doesn't stop you blatantly lying to everyone.
Every time you repeat lies like this it shows how truly pathetic your position is and how truly desperate you are to reject reality, and how little you care about the truth.
Here is an image, which I think I previously used to explain why that statement of yours is pure BS:

Notice how the sun, way off to the right, is able to cast light upwards relative to people at the top of the image?
No, when you look at a rocky horizon, you can editout the mountains mentality and still draw a straight line across to the horizon.
No, you can't.
You can mentally edit out the mountains and draw a line however you please.
You could make it straight.
You could also make it cursive, connected writing.
You are literally saying you will remove what is in the way and just imagine the horizon to be how you want it.
Truly delusional.
What's behind Everest?
The curved Earth.
And by contrast CGI photos often have various types of fisheye warp. But in reality, distant objects don't curve unless a dishonest and/or stupid person is making them up.
Earth curves.
As Earth curves, objects are hidden by the curvature, disappearing from the bottom up.
This is seen in so many things it isn't funny.
Uhhhh, and you haven't noticed that the shoreline is bot perfectly straight?
Why would you expect the shoreline to be perfectly straight?
And you haven't noticed that this bottom up illumination is well AFTER the sun have risen and is high in the sky? What is your explanation for bottom up illumination when the sun is no longer positioned at the bottom?
No, it isn't.
It is BEFORE the sun has risen.
(Or rarely very shortly after it has risen, while it is still "below" the clouds relative to you (not based upon angle to the sun vs angle to the clouds))
Do you have an example of the sun allegedly casting light upwards long after it has risen?
If your BS was true, there should be countless examples.
