Jrjw, so he's on some kind of mix between JW and flat earthism.. That's a strange mix but stranger things have happened.
I would agree with the idea of lots of stupid YouTube videos out there, lots of misinformation but then you have people like Bill Nye (the science guy) also lying and giving false information as a defense of round earth. It doesn't help things when people on both sides are lying and/or making stuff up. I'm no flat earther or ball earther but you have to admit, we've been been fed round earth since being born, just like many have been fed JW info since the same. You can't prove the shape with just a book, that's someone else's opinion. Its worth doing your own research and experiments. If you can't do that for whatever reason, then use your own eyes and observe the world around you in as many ways as you can, and ponder over what you see. And I'm not talking about the apparent flatness. Look up, down, across, everywhere. Take note. Review "proofs" of the various claims but most importantly, prove it to yourself to whatever extent possible. If you can't prove it, then its just information from outside sources that cannot be confirmed. Seek truth and keep seeking, it will find you and you might be surprised by what you see.
Disclaimer: I do not adhere to nor promote any particular shape for earth. While my views here are irrelevant for this thread, I think it's important for each person to examine thoroughly the evidence for ANY claim in which they find themselves highly interested or controlled by, whether religious, scientific, or otherwise.
