Curvature??
Look at the sun in the morning before bright enough.
Well this topic is meant to be curvature, not the sun.
I take it you have realised you have failed and are now trying to change the subject?
Why there are TWO type of sights at the same time: Bright AND Dark.
Care to provide an example?
Bright indicates its altitude is higher than the sun.
Dark (underneath cloud) indicates its altitude is lower than the sun.
The sun lies between both layers.
Or dark indicates that it is off to the side, with some of the protrusions from below creating a shadow.
In some cases a mountain's shadow being cast up indicates the sun is below the height of the mountain.
But notice how this is only in the morning.
At mid day, the sun is always higher than the clouds.
This again would indicate Earth is round.
The sun's light CAN reach 12 hours distance, or half of earth circumference i.e. from east to west.
No, it sometimes reaches more and sometimes reaches less.
At the Arctic or Antarctic circles in winter, it doesn't reach anywhere.
On the equator it is always slightly more than 12 hours.
In the summer it is significantly more than 12 hours.
In the winter it is significantly less.
Also, why would it magically stretch 12 hours?
IMPOSSIBLE for globe model.
No, these are facts which are impossible on a FE model.
It requires the sun to illuminate some regions which are more distant than regions which are near.
A good example of why is the equinox which gives roughly 12 hours of light to all places on Earth, i.e. the sun would illuminate half of Earth.
In your model or the common FE model, this results in the region of Earth illuminated by the sun being a semi-circle.
If the sun really just illuminated a limited distance the region illuminated would be a circle.
This makes it impossible.
Meanwhile, this is exactly what you would expect for the globe model.
Notice the difference between your claim and mine?
I explained clearly why it doesn't work for the FE; you just asserted it is impossible on a globe with no justification at all.
If you are at high altitude, the sky looks like a night all the time.
How do you reconciliate this reality?
I notice how you change topic yet again, further showing you have no confidence in your position or know it is wrong.
Yes, a very high altitude.
Understanding this comes with understanding what makes the sky appear the way it does during the day.
The blue colouration of the sky is due to scattering of light in the atmosphere.
As you ascend to a higher altitude, the atmosphere gets thinner and the atmosphere above you decreases.
This means there is less light to scatter and end up hitting your eyes which makes the effect less pronounced.
Eventually when you get high enough the effect is not significant enough and the sky appears the same during the day and night with the exception of a bright, nearby star called the sun.
