In globitch theory, 21 march and 23 september that the equinox as we know that, sun rises from direct east and sets from direct west.
But this is theorically impossible according to all type of flat maps, including myself.
Challenge:
Observe the sun rising in an equatoral city at an equinox, that september 23 coming soon, and prove you can observe sun rising from direct east.
I claim you can not do that.
Lie: sun rises from east in equatoral cities in equinox.
Truth: sun risrs from "north-east" in equatoral cities at aquinox. Sun rays only come vertical when noon, and never else.

Claim: If you are a gbobist, if you are not a troll, shil or bot; so after research this, you will become a flat earth believer.
Good luck!
