Hmmm, all I saw was a boat slowly sinking into the water...
If the earth is flat, everyone on that boat just drowned.
The boat shrinks down as it gets farther away and close to the end of the video it's so small it's almost completely obscured by the mirror zone. There are plenty of videos taken on cooler days where a mirage isn't covering up the boat.
How come the boat shrinks to invisibility but the sail doesn't?
Magic... Also how come more zoom doesn't bring the ship back into view?
Let's be fair to notbatman, he needs more time to come up with a suitably irrelevant meme for this. Something with hamsters and triple parentheses.
Seems like he just ignored it. I guess no argument was good enough.
