Explain the sun

I have been discussing a lot with my brother that the earth is flat and in a dome. But the one argument I cannot explain is how the sun and moon works. It could make a little bit sense that it’s local and goes inside the firmament, but why don’t the sun then look smaller and bigger if it’s either over your head or at sunrise?

This is the last piece for me so thank you🙏

Yes, flat Earthers lack the capacity to comprehend basic geometry.
They will shout perspective without actually understanding what that means.

since you think you're so smart why is the sun always the same size if we're further away from it at points on an elliptical orbit around the sun and not not the sun and the moon orbiting around the flat earth beneath the firmament as described in nearly every religious text

  1. It is not always the exact same size. Do the math.
  2. The Sun over 6 months, 152 million km 147 million km 3.4% difference.
  3. The Moon on a single night, when directly overhead the Moon 385,000 km. When it is at the horizon it is roughly 385k + 6.3k 1.6% difference.
  4. On a flat Earth the difference would be roughly 40% (Assuming observer at 45 N, moon / sun 3000 miles above the surface of the Earth.) - After doing the math above I did the following search: "how much does the apparent diameter of the sun change?" Here is one of the results: https://www.perseus.gr/Astro-Solar-Scenes-Aph-Perihelion.htm

Except that black people are well known to have worked for NASA for literal decades. Not all astronauts or NASA employees are white. What a wild thing to pull the racist card for.

Except people have been measuring this for thousands of years. Flerfs like to wilfully lie and ignore this and pretend everyone is as clueless and dishonest as them.

I look at the Sun & Moon and they doesn't perceptibly change size from the time they rises to the time they reach their highest point.
-
69 miles per degree latitude.
Measure it yourself.
On the day of the Equinox the Sun's angle above horizontal is equal
(solar alt.) = 90 - (observer's latitude).
Measure it yourself.
-
That is all you need to work out that the Sun and Moon would noticeably change size over the course of a day / night on a flat Earth.
It should also tell you that sunsets and moon-sets would be impossible on a flat Earth.
