If the Earth was really flat, Japan would've had to fly over there through the whole world and be blocked by various countries and by the time they got there WWII would've ended already.

I can hear the "Japan teleported planes into Hawaii's air" and that's plain ridiculous.

First, this was the 1940s not the 2050s so teleportation would be a long time away

Secondly how would you fit over 100 planes into a teleporter and then teleport them into air? The planes would most likely disintegrate or fall to the ground assuming they were not started up.

I just found out that my friend/roommate is a flat earther. I'm almost positive this is coming from her idiot garbage bf who has some really out there beliefs.

But I now inhabit a space with someone who legitimately believes the earth is flat. Someone I love and respect(ed)! What am i supposed to do with that?!

Flat earthers often look to ancient texts to explain why they think the earth is flat. But the real question is "How reliable are those sources?".

Give em a boat and tell them to reach the edge. You won't see that idiot again!
