Specifically, this one.
"Q: "When traveling in a straight direction, you will always reach the same point on the globe from where you started. How can this happen if the world is flat?"
A: You need to have evidence for this to be true. Also, define "straight." Remember, the northern point on the compass is pointing toward the center of the Earth. If you follow your compass due east or due west, ending up at the same point you started from, you have just gone around the world in a circle. Thus, circumnavigation is possible on FE."
You say we need evidence for it? First of all thats kind of hypocritical. Second of all:

I've seen nobody saying anything that even makes sense to back up the conspiracy theory. I mean, the people involved would have pretty much NO motive at all to hide the fact that its flat. There would be nothing to gain and nothing to lose. And yeah I do admit wikipedia is not the most reliable source but they do have those links at the bottom which ARE a reliable source.
Lastly, this website:
