One thing I can tell you tom about this guys the round earthers like alphaomega and other here , they are professional, their all life is about proving the round earth to innocent people.
It looks like it. They are so dumbed down that they won't even look at the videos, as they are afraid that their Round Earth will crumble or they are indeed disinfo agents.
Won't look at the videos? Here's why:
Well I got through 4 videos. Do you realize that boats and buildings that are closer than the horizon will not disappear behind it?
This is consistent with my own experience when I do look at such. Maybe I'm not so dumb after all.
See, what their responses are. There are hundreds of videos like this.
Yeah, and as far as I can tell, they're all junk and a complete waste of time. That's why I usually don't watch them.
Still, it's better to do your own observations!
I will have fun with flags! 
I certainly agree that making your own observations it a good thing. It's especially good if you actually understand what you're observing.
So why the blizzard of links to useless videos?
You guys, love to debunk every video that is posted on this forum.
Yes, we do. It's ridiculously easy, too, if you can bear to watch them in the first place.
It will be difficult to debunk and refute so many (hundreds) videos, showing the earth is flat.
It would certainly be difficult to
watch that many, at least for me. I can only take so much complete hooey at a time, even if it's accompanied with a beautiful or inspiring musical score (that's probably pirated).
Here's a general rule of thumb that I find works every single time: if a video purports to show that the Earth is flat, it's wrong. This has been the case for every one I've seen, without exception, and can be generalized to the rest. How do I know? Because the Earth
isn't flat. It's really that simple.
I would love to see your 10 videos from super zoom camera testing people to display a curvature of the earth by showing the top of ships (not seeing the bottom half) or buildings far below the calculated horizon.
Are videos the only form of evidence you believe? That explains a lot!
You don't take my word for any of this; go outside and make observations. Watching a sunset is easy and would be a good start. Explain how such could happen if the Earth were flat. We can go from there.
I'll tell you what... pick what you think is the best, most convincing (and most succinct, if you need a tiebreaker), of those videos you listed, or any other of the "hundreds" for that matter, and describe its content and/or what new approach it demonstrates that we haven't seen many times before. If it sounds like it might be something new (or at least an interesting new angle or observation) I promise to at least try to watch it. If it's long and there's a particularly significant part, let us know the time that happens and I'll try to at least catch that. No guarantees that I'll make it all the way through, but I will make an honest attempt.
