Just curious as to whether there is any kind of consensus among flatists as to the altitude of the sun above the flat earth.
And, if so, how high is it and how has this height been determined?
Calculating this here
(LINK), I found that it's about 4400 miles. On the second try, I calculated the average altitude to be 4000 miles. But the distance of 5000 miles appears to be a distance that is generally agreed upon.
This is still not an exact value. The reason for this is that there is a layer of water between the sun and the earth, the thickness of which we do not know, and this layer may cause a different perception of height due to the refraction of the sun's rays.

Simply why is this.
Finding the true height of the sun is not easy due to the layer of water in between, but still, accepting a value between 4000-5000 miles as correct will give the least erroneous result. I think you might have started this thread to troll the believers because you are the sleeper cell. No problem. Finding the truth here may be still possible. The rest is not important. I won't respond to citations, most of them are already on the block list. You're not on the block list but it doesn't matter, This answer is sufficient in every way. Objections are not important.
I hope you got the most appropriate answer from all perspectives.
