free-swinging pendulum...

if the earth is flat, and the "conspiratorial" definition of gravity is false, then why does a free swinging pendulum rotate a full 360 degrees over the course of 24 hours?

oh, and while i'm thinking of it, explain seasons lol. really, there is no explanation for seasons other than distance and angle of the sun. with this "flat earth theory," the sun is constantly at the same distance and same angle, year round.

and a third thing...... i know plane flights have been discussed before, but i have to bring this up. Let's use your so heavily relied upon map:

Now, if I was to fly on a direct flight to Hong Kong, going from my home in New York State, flying in the direction towards California, it would take me 15ish hours. Now, if I was to go on a flight over the Atlantic Ocean directly there, it would take me a remarkably similar amount of hours. However, if I was to take this flight over California (which my father has done, and he has pictures of the certain landmarks in California, so I know he didn't fake anyting), by your flat Earth theory, I would have to go across California, then turn completely around and fly all the way back to Hong Kong. How would this be possible if:
A)I would recognize the shift the plane is taking to turn around
B)Going over california, I would reach an ocean. If I looked out the window, I would notice that I am going back over land.
C)Doing that would add significant length to the trip, and whereas with the spherical model, the trips are about the same length, on the flat model, it would take me much longer to go one way than the other. And as mentioned before, my dad has gone to Hong Kong (on business). He has flown both ways before, as he has gone multiple times. Each time, while they obviously are off by a couple of hours, the plane rides are still extremely similar in length. Wouldn't that coincide with the spherical model? And don't tell me my father was knocked out and the government put a digital imaging helmet on his head so they could make him think he was in Hong Kong when he was really somewhere else.

Your father was actually created in the 1960's by Russian scientists who combined the DNA of you and your grandfather. The presence of your father on the airplane is actually a clever means of providing reliable proof to you that the Earth is round (another part of the conspiracy).

Your father was deliberately engineered to be very easy to fool (hence his claim about the flight), but also to seem very intelligent and sane when around you and others you know. It is economically easier for the conspiracy to genetically create people than to built animatronic replicas.

You also forgot the part about all of the plane's windows being small televisions that show footage of the ground going by.
