How do you know somebody else think?
By observing how people act.
I could be mistaken and he could just be pretending.
I am not making up anything.
So you haven't made up any standard of evidence?
Making something doesn't always mean you are making something fictional.
If you weren't making anything up you wouldn't be demanding a full time flight video for these flights, instead you would just accept them.
So no, you are making up standards of evidence.
The reason they are ridiculous and extremely dishonest is because the standard is well above what it would take to convince a rational person of the existence of these flights, the evidence you demand is in no way better than the evidence already provided, and you only apply this standard to things which show you are wrong.
You happily accept all the flights that you can fit into your FE belief, but then when a flight comes up which shows you are wrong, you reject it and demand a ridiculous standard of evidence.
If you were being honest, you would either accept this flight as well and admit your map is wrong, potentially trying to remake it on a RE with an unspecified radius (which as I said before can still produce a FE, where the radius is infinite), or you would reject all the flights and demand a full time video for all of them.
Either way, the honest thing to do is use the same standard of evidence.
Sane person only can be flat earthers.
Not when there is literally no evidence to support a FE over a RE and mountains to support a RE over a FE.
