Nothing yet huh?
Come on guys don’t let me down.
You can't honestly expect people to have time to answer your question, posted in the wee hours of the morning, to be answered within two hours? Somebody'll answer eventually.
Oop, looks like somebody did. As to your unanswered questions:
1) Antarctic 6-month days don't exist on a Flat Earth, and I bet you have no direct proof that it happens. Arctic 6-month days/nights as well as 6 month of darkness in the Antarctic are both fine though.
2. If the sun looks like it sets everyday just by moving far away, then the north start will "set" too, if you moved far enough from the north pole.
