Alright, I'm new, and I'll leave the whole 'welcome me' thing at that.
I don't believe you, any of you. The world is not flat. You want proof?
Start going west from where you live. Don't ask me why. Just keep going. Don't stop and go North or South or back East (you pussy), just keep going West. Never stop. Get a boat. Get a car. Anything. Keep doing it. Still doing it? Don't stop. Nuh-uh, not yet. Not done yet. Oh, where are you? That's right, you're back home.
If the world is flat, wouldn't all of the water just fall off of the planet? Oh, wait, you're going to tell me that there are barriers around the "floating island," right? Some kind of walls to hold up the water and making sure it doesn't fall off?
You're as dumb as Scientologists if you believe that the world is flat.
