Tom, please stop inserting pseudo-mathematic gobbeldygook in your answer.
Why should he stop?
If you compare it with court (like Flat Earthers always do) Flat Earth is not about facts and figures, it is about belief.
"Global conspiracy" is "prosecution", and "righteous minority" is "defendant".
And defendant has every right to defend, including right to lie.
To find the truth is the job for prosecution.
But it goes both ways.
If you are Flat Earther and attack Globe Earth model that works, you must prove it beyond reasonable doubt.
The problem is, Globe Model is not just based on few academic theories, but on the fact that it is the only model where all observations and measurements accumulated for millennia fit together.
Flat Earthers are stuck in desire to find "one final proof that Earth is flat", which is impossible.
Every single local fact from Globe Model COULD be shown as according behavior of Flat Model too.
But ALL TOGETHER facts fit in SINGLE Globe Model, and those other interpretations of those facts require different Flat Models for different subsets of facts.
And there's Space and Space Exploration.
They must constantly deny it and for every new achievement create new ways to discredit it.
For example, direct measurement of Moon distance, whether using amateur radio or radar, is very hard to deny.
Even harder since Apollo missions installed reflectors used now for laser measurements of Moon distance by terrestrial observatories.
McDonald's observatory has Laser Ranging Station, Apache Point another, and I don't know if there's more.
Venus distance was also measured by radar, when Venus was at position of maximum elongation.
(It is position in Venus orbit where angle between Venus-Sun line and Venus-Earth line is 90 degrees.
When you measure distance to Venus by radar, and angle between Venus and Sun from Earth,
you can calculate Sun distance from both, Earth and Venus.)
